Although it is useful to have conscription later in game, I think in this small of a game, it would also be pretty useful to have another mafia to help make kills. Additionally, we don't want to conscript too late, because if a conscripted mafia is the only mafia left, town still wins. So, even if we aren't planning on conscripting someone RIGHT away, I think we should actually do so relatively soon.
My proposed conscript target: Lucy
For the following reasons:
1. Lucy is a strategic player who knows the rules well and is good at plotting. I spent a lot of time last game talking to her as a ghost, both when she was playing and when she wasn't, and it is pretty apparent that she is an excellent player who will be very active in game.
2. #1 is not widely known. Lucy is still a relatively new player, and she has, by no poor play on her part, died early in both of the last two games. So, this means she is unlikely to get lynched from it being sketchy that she's still alive.
3. She has experience being mafia. She was mafia in the Fall 2013 game, and so being mafia is actually not an unfamiliar feeling for her.
4. And the biggest factor, at least for me, is that since partway through last game, Lucy has been my go-to person for blabbing to about all my plots and schemes for future games. This is on the order of hours and hours of mafia fangirling, and it would be really inconvenient if I'd forgotten that I'd mentioned a plan to her and I got exposed as mafia because of it. However, for reasons 1-3 and person player preference, I would prefer her conscripted rather than dead.
