Arkham Horror Statistics Reports

By Tibs, in Arkham Horror Second Edition

Tibs kindly sent me the latest stats sheet, so here we are. I have been working for a while on a Python script that can parse the spreadsheet (in OpenDocument format, the native format for Google docs, that is also the native format for OpenOffice) and then calculate the stats. I initially focussed on the "missing stats", the ones that were difficult to do from a spreadsheet software, and then extended to almost all the stats Tibs is used to post here.

Therefore I will show the "missing" stats, in particular the expansion combos stats and the individual investigator success rates.

  • Cumulated Expansion stats

There is shown the cumulated expansion usage:

Total number of games: 1057
Expansion #games #vict %games %vict %vict with this exp
Base 205 150 19.39 14.19 73.17
BGotW 84 58 7.95 5.49 69.05
CotDP 487 305 46.07 28.86 62.63
DH 631 391 59.70 36.99 61.97
KH 355 207 33.59 19.58 58.31
KiY 450 279 42.57 26.40 62.00

  • Expansion Combination stats

There is the expansion usage, breakdown for all possible combinations

I'll post comments on these stats later.

Just looking at significant stats for combos (where there are at least 20 games played with that combo):

('',) 205 150 19.39 14.19 73.17

('BGotW',) 8 5 0.76 0.47 62.50
('CotDP',) 55 37 5.20 3.50 67.27
('DH',) 152 93 14.38 8.80 61.18
('KH',) 48 27 4.54 2.55 56.25
('KiY',) 34 25 3.22 2.37 73.53

('CotDP', 'DH') 72 53 6.81 5.01 73.61

('DH', 'KH') 33 19 3.12 1.80 57.58
('DH', 'KiY') 51 31 4.82 2.93 60.78
('KH', 'KiY') 24 19 2.27 1.80 79.17

('CotDP', 'DH', 'KiY') 63 43 5.96 4.07 68.25

('BGotW', 'CotDP', 'DH', 'KiY') 36 27 3.41 2.55 75.00

('CotDP', 'DH', 'KH', 'KiY') 177 93 16.75 8.80 52.54
('BGotW', 'CotDP', 'DH', 'KH', 'KiY') 23 15 2.18 1.42 65.22

Unsurprisingly, adding an expansion to the base game increases the difficulty (in particular DH and KH), except KiY.

But there are surprises: ('CotDP', 'DH') is more successful than DH, meaning that CotDP makes DH easier than DH alone! This is confirmed by ('CotDP', 'DH', 'KiY') as well. Maybe only experienced players play these multiple expansions? On the other hand ('CotDP', 'DH', 'KH', 'KiY') is the hardest combo! Strange, isn't it ? Of course, we need to be careful when the number of games is low, because the statistical variations will be higher.

In term of number of games, it is natural to see combo frequency follow the order of expansion publishing date. But there are some peculiarities: there are few "out-of-order of publication" games, such as DH + KiY or KH + KiY. There are more CotDP+DH, CotDP+DH+KiY, etc which means people don't bother separating their extensions after purchase. For instance, there are more ('CotDP', 'DH', 'KH', 'KiY') than any other combo, even DH alone! It means that people "accumulate" their expansions and they do not remove them afterwards.

  • Investigator popularity and individual success

I let you draw your own conclusions and comment them.

If some people have ideas of other stats, I'll be pleased to add them to my script (as long as they are not overwhelmingly too complex).

('BGotW', 'CotDP', 'DH', 'KiY') 36 27 3.41 2.55 75.00

Am I reading it right, 36 games with said combo, 27 wins? Hehe, I think I contributed quite a bit then, as my last 24 games were using that combo and only 2 losses.

Haha, KiY makes base game easier, lol.

I can only speak for myself, but I'm way too lazy to start separating expansions and then mixing them in again, making sure they are shuffled properly sonrojado.gif . Seems kinda redundant.

The three worse investigators in the game are Vincent, Sister and Charlie Kane (as popularly played). I've always considered them a drag on a team. Time to reimplement my house rules to make them more playable.

Vincent can heal anyone in town if he's in town too. Sister doesn't lose her blessing and Charlie (well I won't mention what I do with Charlie).

Daisy Walker at 60% probably means most people haven't discovered her spell yet.

I'm kind of surprise to see Amanda and Jacqueline so high in helping their teams. Maybe not Jacqueline. She really saved us a lot of Mythos trouble in our last game.

To Zeb: The stat I always extrapolate is the chance of winning by seals/close vs. battle for each AO.

I think people who draw Mary just "give up" and play her poorly, because they hate her. For me, Mary's always good gui%C3%B1o.gif .

Also, WTF is up with Amanda Sharpe and her 75+% sorpresa.gif ? No effing way! Or maybe I just play her poorly 'cos I hate her sonrojado.gif .

I think that Tibs already provides the chances of winning during Final Combat for each AO. But I can work out the other ways to win.

I use that stat to extrapolate my figures. What I am interested in the chances of winning by seals/closing when entering into a game with a particular GOO. If you look up higher in the thread you'll see my extrapolation. My extrapolation is not exact: It assumes every game is either a seal/close victory, a final battle victory or a final battle loss. Other wins and losses would be interesting.

I've included chances to win by Final Combat, and chances to win without the AO awakening (The entry on my last report is Most Restless ). This is essentially a combination of chances to seal and chances to close.

I didn't bother to differentiate between winning by closing vs. winning by sealing, because their relative chances are probably not based on the AO so much as the number of players and overall luck of the game. Only Hastur, Yibb, and Atlach should yield a significantly different ratio, but it might be worth investigating for anyone who cares.

Would it be possible to add a field for Scenarios? Especially with a 'Custom' entry, that would be really helpful.

I think flamethrower49 took everyone's recommendations about expansions seriously. All of his submissions have been with the Dunwich Horror and King in Yellow expansions. He's also climbing the ladder like a maniac.

I love these.

I only wish I had time to do the league and attempt the unbeaten combinations!

Is there a good way to get comprehensive rumour statistics? Like which rumours contribute to the success or failure of the investigators? That sounds interesting.

Last time I updated the forum, I entered checkboxes for passed or failed rumors. The best I can do for now is wait for a significant number of entries, and then reveal how often each rumor is passed or failed. It would be really difficult to correlate how these affected the entire game's outcome.

Kudos again, Tibs. Very interesting stuff. A suggestion though, flamethrower49 and myself agree that we'd be very interested to see a new column of % games won-lost with certain Rumors passed/failed. Kind of a 'deadliest rumors' kind of thing. Also, #4 baby! yeah! Dam, we're gunning for you!

1193 games. 32.9% used Kingsport. Only 19 games had any rifts open. That's less than 5%. I had 4 of them and Tibs had more than me.

Interesting.

It's interesting to me that nearly 1/3rd of games use Kingsport and that the rifts are so fearsome that we keep them very well undercontrol.

Almost as many have been Changed (17) as have seen a rift in action.

Tibs Thanks for the reports. I look forward to them!

Hehe, as I've said before, my last game was in mid-December. Also, doesn't look like I'll be going from 72 to 84 (7th rotation of AH + DH GOOs) anytime soon, Age of Conan should be in stores this month, looking to get Lord of the Rings TBG as well, maybe May will bring a change with Innsmouth, although the Dungeon expansion for Talisman is also scheduled for May, so who knows. Most likely it'll be summer when I next crack open my AH preocupado.gif .

Well guys, I have responses for you--

flamethrower49 (and friend):

You can see my stats submission page includes rumors. I wanted to wait for few stats reports before reporting on the rumors, so that I can gather up a bit of info.

Mageith:

I put the exact number of instances of open rifts and other events on the list instead of % of games for a reason. Those are the number of reported instances of opening rifts since I added that option to the stats page; it's not meant to be turned into a percentage. Every one of the submissions I've personally made was after I'd gotten Kingsport, but the "rift opened" check box was added fairly recent.

Sweet. I didn't realize that Yog-Sototh/Black Goat was on the list. Good for us!

I think it's interesting that the still-undeafeated combos seem to be people looking at the Kingsport Ancient ones and the Black Goat and saying, "Nuh-uh." I realize that most of us play random, as well, but I think I'd be tempted to try it, if I owned Kingsport.

Kingsport is currently being translated into German. I really hope it gets published soon - I want to try all of those new combos!

Thanks again for the report.

All games? or is this the percent of games since you started recording it?

Since recording that feature, so it should be pretty accurate. I implemented that percentage just for you ;)
