I'd love to play/host YCI2 should it ever happen. It was the first mafia I spectated on Smogon and caused me wanting to play as well. For my favourite mafia games: Pokemon Mafia was the best because OUR TEAM was awesome and in high spirits for the whole game, also it was challenging. Pokemon TCG Mafia is the one I put most effort into, it was really competitive. Metal Gear Solid Tactical Game was fun because Exarius/Accent played along my troll civilian role. But more fun than any of those has been Smogon PFS. For my very favourite Circus game I put Philosopher's Stone War I. It was my first D20 roleplaying ruleset experience and it was a blast of creativity, sleeping in trucks and cooperation. Also the encounter where I died (me as Isaac Newton/Aura Guardian as Saint Anthony versus Lightwolf as Tyr/ginganinja as Robin Hood) has become a legend.
