I've played five games so far, of which three I was a cylon, one 4-player, one 5-player and three 6-player games ... all cylon victories.
Humans versus Cylons: Victory Count
Cylons 3, Humans 1
A couple of the Cylon wins have been real close though, with 2 of those games having the humans one jump away from winning iirc.
As of now: Cylons 1, Humans 2
This is by the rules. We had one, where we called it a draw, 'cause we forgot to take the Admirals post when he went in the Brig - if we could make choices in "Admiral Chooses" and we could use the nukes - then humans would probably have won.
...Idless
2:0 for the Cylons, both times the humans were way beyond rescue.
Humans 1 - Cylons Nil so far. But it was very close.
Six players. Didn't help the Cylons that one of the toaster players had such a bad 'poker face' we suspected him straight after the sleeper agents phase (
)
Game was six hours! Hopefully we can get that down to 3-4 next time.
Now currently up to 2 Human victories and 1 Cylon victory. All these games were 4 player games.
Meant to add the break down for the 3 full games played so far. As stated earlier all were 4 player events.
Game 1 - Helo, Boomer, Baltar (Cylon), and Apollo. Result = Human victory
Game 2 - Tom Zarek (Cylon Sympathizer), Starbuck (Cylon), President Roslin, and Colonel Tigh. Result = Cylon victory
Game 3 - Tom Zarek, Commander Adama, Boomer (Cylon and Sympathizer), and Chief Tyrol. Result = Human victory
Boomer didn't pass on her Cylon card?
Very true. My wife played it quiet and never revealed, hoping to do more damage being sneaky. While we never identified her, and thus she kept herself out of the brig, she didn't do enough to keep the cylons ahead. The humans won.
Played two games now.
1 - Humans : Cylons - 1
I was human in both games. Both games were 6 players. Last game, by the time we'd been round the table once we were down to 4 undestroyed vipers. Still it was close, we got to just before the final jump when we lost all our morale (Boo...)
Loving this game, both plays so far were utterly different and now we're all familiar, the play time was down to just over three hours (first game was nearly six).
Seen lots of posts likening this to Shadows Over Camelot, which I also own, but to be honest, apart from the traitor mechanic, they're poles apart, and BSG is by far the more fun game.
After another 6 or so games and much more experience around the table, it seems the humans have gone on a 5 game winning streak. The last one being particularly easy, a 3 player game with no cylons to start as we soon figured out. So everything was in place for the midway point and the new cylon basically had a huge amount of work cut out for him.
Human 2 and Cylon 3 for me. I do not count a game when another player by accident put 3 cylon cards in a 6 player game. I was playing another game at the moment and he thought there was 3 cylon cards total and therefore only removed one of them. 
Played 3 games so far, Cylons have won twice and humans once.
So far, it seems the cylons have had every advantage. I was the cylon in our most recent game (4 players).
The characters were
Starbuck: Cylon (me)
Roslin: Human
Tigh: Sympathizer (became cylon)
Boomer: Human
The humans only won because I didn't want to reveal myself on the very first turn. All the cylon units were on the board after each of us had had a turn (2 cylon attack cards and each basestar launched twice) which was clearly the perfect time to reveal, but we had only been playing for 10 minutes and my friends aren't the types to want to start a new game right after finishing. For us, it's more about the experience than playing to win so I decided to help the humans out (at least, as much as they asked me to help; I wasn't throwing out any useful ideas
)
Anyway, we got away relatively unscathed and there were no more attacks until after the sleeper agent phase. Tigh got the sympathizer card, became a cylon and the admiralty passed to me. I led the humans to two destinations at 1 distance point each at which point they started suspecting me. I got lucky on a crisis and threw the president in the brig and accused that player of being a cylon. Poor Boomer had no clue who to believe because aside from my poor lack of direction as Admiral, I'd been a strong supporter of passing all the skill checks and fending off raiders when they were around.
Anyway, after a few more turns she tried to put me in the brig too (and as Starbuck I knew I didn't have much of a chance to resist) but luckily the attempt failed, but I saw that as the time to reveal.
I damaged galactica, went to the ressurection ship and started hammering the humans.
Boomer got lucky and managed to get 3 distance points closer to kobol and it brought them to 8.
Roslin got out of jail and all the resources were around 2-3 and Galactica had 4 damage tokens on it. There were centurions on board and they were halfway there, but Tigh and I just couldn't decide how best to hurt the humans.
We decided to keep hitting the human fleet location to try to take out their FTL drive and steal repair cards so that boomer couldn't repair it, but we were unlucky.
Galactica made it to the -1 pop location and jumped.
So humanity was reduced to about 1/10 the population, they had little to no morale, very little food and no fuel (probably) by the time they reached kobol and the centurions were still kicking around but they still had cause to celebrate!
Anyway, fun was had by all (even me though I was a bit frustrated at myself for not revealing sooner to give myself more turns to hurt the humans) and it was a good game.
Another victory for the Humans for our group this weekend! I believe we stand Cylons 7, Humans 2.
This one was fantastic..........3 resources were down to 2 or 1 for 2 full trips around the table. The Humans passed skill checks of 15 and 13 to ****** victory from the jaws of defeat.
So far:
Cylons 7 - Humans 1
The human win was a close one and was on the best game config for humans, 5-player - with the cylon wins being in various game numbers (6,6,5,5,5,4,3) with the sympathiser a cylon in both those games.
In our group we don't have Cylons often from the beginning and the human players use everyhting they have, so mostly before the sleeper phase the humans have more resources than they began with.
So in our group humans have won more often, but since there are so many ways to loose for the human side all in all it is mostly balanced (with perhaps the exception of 3 player games where you have a Cylon from the beginning).
Cylons: 5 - Humans: 9 (or somehting like that)
We had several games that were won by the humans with the last die roll.
Four games .. (two different groups)
Humans - 3 (all very close (several resources at 2 or 1))
Cylons - 1 (A centurion loss since it was 2v2 and the two humans couldn't roll a 7 or 8 for a few turns in a row!)
Hehe too bad we couldn't make a multi-option poll to show the actual statistics of human to cylon win/loss. Seems almost universal that humans don't have it so easy.
Humans 1
Cylons 4
We had a 5 player game yesterday - another clear one for the toasters. That's 6 games total, all cylon victories. Only one was close. I start to wonder, if the humans have a chance at all...
I just got my first game in on Friday night. we played the 2-player variant because we always play the 2-player variant to make sure we have the game down before introducing it to others. We had a human victory but mostly because neither of turned out to be Cylons. So not sure if that counts 
In the 5 games I've played in I beleive it's been Cylons 3, Humans 2. However from the way the last two games have gone I would expect the human count to increase much quicker given the same players as before.
We've only played it twice, but so far it's Cylons 2 - Humans 0. The first game was rocky, but all six of us were new to the game so we were still learning to play as we went. The second game went very smoothly and the Humans were looking very good going into the Sleeper Agent Phase, having all resources still in good shape except for Morale dipped one point into the red intentionally to prevent a sleeper agent switch.
Unfortunately for the humans, I had planned that all along, having the -1 morale You Are a Cylon card. I waited for the first -morale crisis to come up after the sleeper agent, shot my hand to make it fail and then flipped. They got to the last run before the final jump, but I had managed to wreck them a little too efficiently. In the turn before my big reveal I helped cast suspicion on others and managed to get Admiral Adama and Tyrol brigged under suspicion of cylon activities. As soon as I could I Resurrection Ship'd my second You Are a Cylon over to the President, and with half of the humans in the brig it was just too late for them to do anything about it.
It does seem that Cylons are capable of some truly epic plays that can turn a reasonably painless human game into a lopsided victory. But then, had the humans not been so paranoid to brig so many innocent people, things might have turned out much better for them. We'll certainly be playing it many more times.
Incidentaly, I discovered that the best ally when you're a hidden cyclon is to have a colorblind player at the table (as we have). A couple times he accidentally threw the wrong color card into the pool on a crisis which cast suspicions everywhere else but towards me. We rationalized it with our new house rule - "Helo's kind of a moron".
We played for the first time on Sunday and again on Wednesday.
The first game featured five players and ended with a Cylon victory just as the humans were beginning the final jump phase. However, the Cylon victory turned out to be somewhat illegitimate since, apparently, an extra "You are a Cylon" card had gotten mixed in with the "You are not a Cylon" cards when the loyalty deck was created.
So, although only one Cylon was revealed during the course of play, there turned out to be two more unrevealed Cylons who spoke up after the humans lost - meaning that the Cylons had outnumbered the humans 3-2.
The second game played out properly and again featured five players. This time the humans achieved a narrow victory; finishing the game with, I believe, 1 Fuel, 1 Food, 2 Moral, and 2 Population. 
So in the meaninglessly small sample of our sessions, the Humans and Cylons are sort of tied 1-1, although the Cylon victory arguably doesn't count and the humans could, therefore, be considered in the lead. 
2 Games on Saturday night - (Two Cylon Victories) Player count: 6 with 2 newbies (however experienced board gamers)
1st game Cylon victory, but VERY close:
Characters: (In turn order) Chief, Apollo, Starbuck, Roslin, Zarek, Tigh (me)
Game started out well as nobody pulled a Cylon card at the beginning. As luck would have it, we pulled the Crisis Card with 1 destination within the first couple turns. Next, as Admiral, I took us to to a 2 destination first, then after the second jump, our resources were still high, so I took us to the Icy Moon, just in case I drew the Sympathizer. Turns out Apollo was the sympathizer. Funny thing though, the one Cylon (Starbuck) figured me to be the other Cylon, because of heading to a 1 destination just before the sleeper phase, so he attempted and succeed in Brigging Chief, who after two attempts to get out, ended up revealing (this was two jumps later with the distance at 8, btw). All looked doomed for the Cylons, until it seemed the Crisis Deck, even with Roslin as a human, didn't give us anything on the Jump Prep track. The newly revealed Cylon activated the basestars and damaged us once (armory). With no centurions on the board, we were in the clear. The Sympathizer activated Caprica, and we had another Cylon assualt on our hands. However, population was at 3 and we were one away from using FTL. Then the 2nd Cylon finally revealed, damaging command and weapons control. We were without defenses as our two pilots were gone. 3 turns later, i was ready to pull FTL, but on Roslin's turn, neither card on the Crisis Deck were jump preps. Then it happened, on Zarek's turn, raiders were activated and 3 civi ships went down, well, what do you know... one had -2 pop another had -1 pop... game ended, Cylon victory.
My take: Although my team lost, we agreed it was the best game so far because of the tension during the last round of turns. Had those civi ships not gone down, I would have pulled FTL on -3 with strategic planning giving us 50/50 chance to win. And no, I did not roll the dice to see what it would have been.
2nd game Cylon victory, no chance for humans:
Characters: (In turn order) Helo, Zarek, Adama, Chief, Boomer, Starbuck (me)
This game was the opposite of the previous... I drew a Cylon card. Being Starbuck, I knew it was going to be tough to stay in the clear for long. Through the first few turns, I just sort of stayed under the radar and did not put cards into the skill checks claiming i could not help... that was until there was a chance for -2 morale.. i played my 5 strength tactics card and screwed them over. Since most characters drew Tactics, it was hard for them to know who it was, but since 4 cards counted negative, they were pretty sure there were 2 cylons already, and since i only put in one card, I knew there was someone else already, making it easier for me to reveal early. We had them so scared of there being two cylons that they intentionally didnt put cards into skill checks thinking they would fail anyway, so by the time I revealed on my next turn, the morale was at 6, population at 8, fuel at 7, food at 7 i believe. Turns out i was in sickbay. I asked Chief to EO me out of sickbay so I could get my full skill set. I used the EO to get into a viper. At the start of my turn, I was Starbuck in a viper, so i exited to Galactica, pulled FTL at -3 population, then with my second action, I revealed dropping morale by -1. What do you know, the Admiral was the other Cylon, so he intentionally took them to the Icy moon only taking destination to 3 total. To make a long story short, the rest of the game was us two cylons messing with the rest of them. They knew that the morale and population were already too low to survive 5 more distance and one last jump. They lasted about 3 more rounds of turns before two cylon attacks, and a colonial one bomb (thanks to me) destroyed their morale.
My take: Fun for Cylons, but not for humans. They knew once I pulled that FTL, they would not have enough resources to last, so playing the game was almost a chore... however, some things to take away from this game:
(1) Early in the game, don't intentionally lose Crisis skill checks thinking it would be a waste of skill cards. Those resources are limited and early on, you have no idea what they will look like later in the game. Later in the game, at 7 or 8 distance... that's when you can start determining what resources you can do without. (However, we have yet to play ONE game where Food was an issue).
(2) Don't let the excuse "i can't help with this check" fly by without questioning that person, especially if that person is holding onto more than 3 skill cards. At least make sure all players are aware this person "is not able to help" with the skill check.
Just started playing so we only have three games in, and part of a fourth (we had to stop early because dinner was cooked and more players showed up). In the three games we finished, we ended up Cylons 3, Humans 0.
The first game had five players - in order we had Apollo, Bill Adama, Roslyn, Chief (me), Helo. For the beginning of the game, everything was going great and we decided that either there were no Cylons or that we had one playing it very subtle. Knowing what I knew about the players, that counted out at least a couple of them, and I knew I wasn't a Cylon. Once the Sleeper Phase came around, we dealt out cards and I got hit with a "You are a Cylon!" card. Excellent - I love playing deviously. Well, Roslyn got a card that allowed her to see one of my loyalty cards and she put it down and said, "Yup... he's a Cylon." I shot back with a, "Guys, I think we've got a problem. I'm not a Cylon - I think Roslyn's a Cylon." My turn came up next and I tossed the President in the brig, everyone siding with me. Roslyn's character started cursing up a storm, but by then, the fleet was getting surrounded. Apollo realized the mistake and tried to get Roslyn out of the brig, but failed. More ships appeared and Roslyn tried to get herself out of the brig, but I blocked it, and more skill cards went to waste. At that point I jumped to Colonial One and tried to get elected President. The last of the skill cards were depleted in blocking my attempt. By that point, the base stars were just pounding on the ship, and I, being the only engineer, wasn't fixing anything. Six damage chips later and the Battlestar blew up.
The second game had five players too - in order we had Tigh (me), Chief, Baltar, Starbuck, Apollo. This game started out with three or four piloting cards being tossed into one of the skill checks against us, clueing me in immediately that there was a Cylon, and that it was either Starbuck or Apollo (Baltar wasn't drawing any piloting cards). I announced that at Baltar's turn and Starbuck chucked Apollo into the brig. During that Crisis check, four negative cards turned up, so we knew there was another Cylon in the midst. I was confident it wasn't Baltar - he had been helping us pretty well so far - and had a hunch it wasn't Starbuck as soon as Apollo revealed himself as a Cylon on his turn. My turn came around and I chucked the Chief into the brig. He revealed himself immediately after and the humans all smiled - we'd rooted out the Cylons before the Sleeper phase even came around! From there everything went downhill. The Cylons pounded on us relentlessly and ended up bringing their fleet around to bear, destroying a bunch of civilian ships and dropping our population to zero.
The third game had six players - in order we had Boomer, Bill Adama, Roslyn (me), Starbuck, Chief, Baltar. I drew an Arrest Order as my Quarom card. Early on, I don't think there were any Cylons. We cleared the table pretty quickly and hit the Sleeper Phase with everything above half. Boomer got the Sympathizer card and jumped to the Resurrection ship. From here, the suspicion started to build. By this point, the humans had one resource in the red and were already six spots from the end. I knew Bill wasn't a Cylon (or he was being a terrible one - he was very overtly working for the humans). Baltar accused Starbuck of being a Cylon, but couldn't get the votes to get her in the brig. On her turn, she tossed Baltar in the brig against his protests. At this point, Cylon-Boomer gave me her unrevealed "I am a Cylon" card and switched me to the other team. I played casually at the beginning, picking the Crisis cards that had no moving on the jump track and grabbing a few Quorum cards until I had another Arrest Warrent and all the while vocally trying to figure out who the Cylons were. I blocked every attempt for us to get Baltar out of jail, constantly accusing him as he accused me. The jump track wasn't moving much, and our population kept dwindling as Cylon Basestars jumped in to the area. All our ships were getting damaged and I decided to make a move. With Starbuck out in space, I tossed the Chief in the brig, claiming that he was responsible for stopping one of our skill checks with his horded politics cards. The Chief was played by the same guy I brigged the first game, and he started yelling that I was a Cylon again and explained my whole plan - get everyone who could brig me into the brig. If Bill was around, it didn't much matter, because he couldn't get rid of me. Skill cards dwindled as people tried to break out but with me, Boomer, and one other mystery Cylon working against the attempts (I was pretty sure it was Starbuck by this point), they never got anywhere. Raiders kept swinging towards about six civilian ships with only Starbuck in the way of one batch. My turn came around and I brigged Starbuck to get rid of any defenses in space and drew two Crisis cards, favoring the one that moved the Raiders. Five Civilian ships died that turn, bringing our Population to zero.
All in all, good games. I ended up being the Cylon twice in three games, though. I liked being the humans more, I think. Fighting against a losing battle and doing the best you could was just a lot of fun.
