Short version:
Chocobo Racing (FFVII) vs. Blitzball (FFX) - Fuck Teebopo or whatever in hell his name was. That is all.
Drinking Root Beer (CT) vs. Stupid Judgement Ring Shit (SH) - Because you never need to do it, ever, and while some of the SH stuff is pretty okay, other stuff is just blah.
Sidejumping (LoL2) vs. Bunny Racing (SO3) - Was Sidejumping the press X or press control sticks one? If former, it wins; if latter, Bunny Racing wins.
