Sunday I ran the first half of Final Sanction, here's some feedback:
The hordes system works basically but it gets dull when there's plenty of hordes fighting involved. Turning points or random battle event tables are a must then. Other than that, it might be better from a game mechanics viewpoint to let the Brothers fight a single menacing horde than an endless stream of less challenging hordes. The latter, as mentioned requires work from the GM or scenario author to break up the numbers crunching.
One point that came up during fighting hordes was ammo consumption. If there is a let's say about 3 to 1 rate of actual horde members and horde magnitude, it's not believable to assume that each shot that hits (reducing horde magnitude by 1) actually kills 3 enemies. In short: reducing a horde like the ones in FS seems to ask for higher ammo expenditure but that's probaby a house rule. Right now I am considering adding another attribute to hordes: horde density.
Also to give the player an impression for the kills they have inflicted I had let them roll a d3 after each horde hit. I multiplied that roll with the magnitude damage inflicted and totaled that up at the end of the session to give the players an estimate of their body count. The Devastator had one of 230 kills.
Anyway, for shooting at hordes I don't adjust for horde size but for how much a horde of a given size is exposed to the shooter. As a result I apply a modifier of +0 (small or severely decimated horde that's entrenched) to -30 (huge horde in the open).
Demeanours are doubtful. To be fair: without guidance by the corebook, it's been hard to figure out how to properly roleplay the Marines (Personal vs Chapter Demeanours - which takes precedence and how much can you stray from your Chapter) and all and it has been an improvise session too besides. Demeanour appear right now to be a cheap way to get an additional reroll. It didn't came up during play but I predict the improvement voting won't work: players will always be inclined to vote with yes. Either because it's to the group benefit (thus their own) anyway and more importantly because they won't want to cause any bad blood, possibly leading to them being down-voted next time too.
Overall role-playing was little but that's largely owed to the scenario and the aforementioned difficulties of getting into being a Space Marine without good guidance.
The session had two highlights, both thanks to the Dark Angel player. The first was 'Breaking Point' turning point. The Ultramarine failed to raise the morale of the troops, thanks to botching both the fellowship rolls, as well as causing his weapon to jam after delivering a supposedly rousing speech. The Dark Angel player made a very good Int test though and so I told him (especially since it's the introductory scenario) that he needed to do sth totally foolhardy to raise the PDF's spirit. He made the right choice and left cover. He won the turning point for the kill-team in the end thanks to his Stoic Defense ability.
The second highlight was I described how Captain Ascote took them aside and, took of his cap and started changing in appearance. The Dark Angel player, apparently fearful of Genestealers, shot Syndalla right in the chest with his bolt pistol. She fell to the ground in disbelief, severely wounded and when she made motions to get up (now as a woman), she was shot again, this time fatally I ruled. Yep, they actually killed Syndalla before they had a chance to speak.
They can only be glad that her Inquisitor isn't around to punish them for that. (What punishment is there for SM actually? Tribunal before the chaptermaster?)
The feedback of the players was positive but don't read too much into that: it has largely to do with never having fought with character against such a fast number of enemies and killing so many so quickly in a firefight. That part will get old quickly, I expect.
In the end they went towards the PDF HQ and failed to stop the siege thanks to some bad luck because I managed to pass the morale checks twice in a row.
Anyway, I preordered the Rulebook on Monday.
