Tic-Tac-Toe on paper? Wait, no.
Well, I've been playing around with SNES, Genesis, 64, and GameCube titles, along with plenty of classics on PC. Honestly, the newest game I own is [Prototype] (aside from Sonic Generations, which I got for Christmas, and won't run). And, even before then, I think my newest game was Plants vs. Zombies (2009, but 2010 "Game of the Year" edition) followed by Sonic Riders from 2006, Shadow the Hedgehog from 2005, and, before that... 2004's Sonic Heroes.
Maybe, 007: NightFire (2002), before that. Man, when were the rest of my GameCube titles from?
