lol what I can say, I love mafia and being able to play full games makes the game that much more exhilarating. Dying night one every friggin game gets annoying. =P It's like, you can't even get into it because because you're dead before anything important happens.
So yeah, being bulletproof is by far my fav role to have. I'd rather have to die either as punishment for screwing up, or by being out persuaded by someone, not just because mafiats/SKs/vigs are afraid of me or don't trust me and just don't want to have to deal with me. XD
Sort of in tandem with loving being bulletproof, being an SK (who are typically bullet proof) is another favorite role of mine. I love the freedom of playstyle it allows for.
