Roles: I would have to say that NOTW games again probably took the crown for some of the most powerful roles, like the most powerful mafia teams or serial killers and so on. But lots of good ones out there, I'll choose two roles from two good games.
Darth Maul, Star Wars
Paranoid General (Decker? choxorn's role iirc) from Mars Attacks
Best Hosts
Zack - as mentioned before he already did so much work organizing/recruiting folks into more mafia games, but he also hosted multiple good games himself.
Camikaze - would certainly look forward to another one of his games in the future, well designed and detailed
