I'm going to be honest with you guys, I've never really considered buying an OUYA. Something just doesn't sit right with me. That was until Matt Thorson sat me down and forced me to play TowerFall. Now I want an OUYA.
TowerFall isn't a game that's hard to understand in theory. You and three friends run around in Super Smash Bros.-style stages and shoot a limited number of arrows until everyone but you is dead. In practice, TowerFall features a mind game that would make a member of the FGC blush, and a deceptive level of depth.
