Def PS2 of course. I'd also say FireFall is popular now and there are a few Dota 2 players. Would agree on Heroes and Generals too. Our Star Citizen activity will increase as development goes on so I'd add that. Arma 3 used to be a big thing, I think it's diminished a bit in our community due to half of our old active arma 3 players are now less active.
