The Syndicate

I agree with the sentiment regarding civs who play as individuals, because I'm guilty of it quite a bit. I pretty much invest everything I do with storytelling, and Mafia lends itself well to that, so I think within the bounds of the story and don't really think of it as a victory if my character dead at the end. I'm reluctant to even put banners in my sig of games where I won even though I was dead (I do have a couple, but they feel like technicalities to me).

It's easier for me to sacrifice myself for teammates I know (eg. as a baddie), since at least I have some concrete purpose for my death. But yeah, I'm definitely part of the problem.
