Just joking. I don't play games that much, so I can't really consider what's best.
Well, my vote would go to Final Fantasy Versus XIII though. Just saw the trailer and it's simply breathtaking.
Overall, I'm gonna say Just Cause 2, actually. It sure ain't technically better than, say, Rage or Crysis, but to see that game in motion, cruising over the water in a military jet and the hundreds of explosions going off on the beautiful island beaches... yeah, Just Cause 2 for sure.
