Aah I am a GM I shouldn't need to come up with lies.
(For those unsure what I am referring to, pravinas had not actually expressed interest in playing Live Action Mafia, but I thought that patg dropping without using up her 2 kills would be too much of a hit to mafia, and I might not have bothered to replace patg if she was town.)
I'm not sure what I would do if I were to GM a fall game in the future. Certainly I like the idea that roles are basically just randomly assigned, and that a new player that no one knows has the same chance of being serial killer as anyone else. But it is definitely a problem for balance if a serial killer drops without so much as making one super obvious kill. Maybe I'm failing to see some option, but I don't think that there is a better option, even in hindsight, than either compromising game randomness or letting inactivity make game notably unbalanced in some particular direction.
I guess one thing I will say is that it is good for GMs to be consistent about how they handle inactivity issues, and not just only fix things if it's a mafia dropping. I think this would be sketchier if I hadn't already replaced a dropped townie, and if I hadn't previously compensated for dropped townies with balance changes, rather than just saying that dropped townies didn't matter. I'm not sure, but I think counterfactual me at least with good probability would have done something if a townie said they were dropping as well. I am now more convinced that even if it's not very important in terms of balance, it is important in terms of consistency.
Meghal at least said, "oove, another active player we gotta gao," so I'm hopeful that other people won't be suspicious either!
