Ohh yay, the town won. Like expected, but closer than I thought.
On the other hand... it was 6 townies VS 1 BO in the end, right? Even with Vermouth being near indistinguishable from real townies then (she is a Camel with crimes after all - so X-Examine, SI, Investigate and other abilities could still find her). I don't see a reason to change anything with her killing ability. The town also has a good chance to win if all they have left are Observers, Healers, Tricksters and Protectors - meaning town roles who can't find disguises, crimes or BO - and in that case it would not matter which BO is still alive. This game was mainly so close because of townies not participating much and because of Paix managing to almost slip though the town alliance precautionary methods. So unless it happens again (or a GM does not want to have something similar occur) there is nothing that has to be changed.
If there is anything for the new game it would be the following: Sonoko can't befriend Vermouth anymore, that was introduced before APTX was around and makes not much sense gameplay-wise anymore.
About Anokata arresting: Sure, why not. But as said before: BO
and their allies should not be able to arrest for blamed actions. (And making blame not a crime anymore sounds like a good idea as well).
Question is: Should Calvados be able to copy (back-up) arrest from his allies? If Anokata gets it, why shouldn't he get it as well.
Finally, on the subject of criminals: I think they should remain in our mind. However, they should only be used in games with many participants. I think that in games with less than 25 people they would be too imbalancing and should not be in those rounds. However, in case we get a round with 30 or more players we should have them, since they are able to speed up big games a bit and make them faster and hopefully a bit more enjoyable as well. Because in a 30 player BO VS town the BO either wins in the first 5 days (which would mean they have to kill an aweful lot of players or start with an unfair number of members - which usually coincides, since many BO means more ways for them to find identities) or we get a game where the town dominates the game but still needs weeks to weed out the remaining BO.
