Any and all Sports games - Football, American Football, Basketball, Baseball. I care not for any of them.
I got a copy of Fifa 2010 when my 360 died and I bought a replacement, but I didn't touch it, and the £20 I got for selling it probably bought me something that I was interested in.
On another note, I had no idea that Baseball games were as popular as they are. According to
this source, MLB The Show 21 is the second best-selling game of the year. I'd never even heard of the franchise until this year, too.
The same goes for Skateboarding games, too. Everybody seems to have crazy nostalgia for the Tony Hawk Pro Skater games, and the Skate games were really popular amongst my group of friends, but that particular genre just completely went over my head.
I've also never touched a Resident Evil game.
