Oohhhh...... gosh. That's quite the toughie. Well...
Motorstorm: Apocalypse
I loved pacific rift, but this game just looks crazy awesome. Big City? Check. Explosions and environmental hazards? Check. Two factions which will try and destroy your car any way possible, along with a PMC that will also get in the way by trying to stop them? Check. So far, so good, but then to top it all off they said that the game would include MOTHERFUCKIN' CHOPPERS!?! YES!
Deus Ex: Human Revolution
It's got the cool story, and the human augmentations, and the distinct vsual style, but you know what else this game has? Replay value. In absolute truckloads. You can talk, shoot, or stealth your way through the game, and I'm pretty sure that that's not even scratching the surface.
No More Heroes: Heroes Paradise
When I was younger, I was that kind of kid who would look at youtube videos of game and just enjoy it, and No More Heroes, well....It just stuck with me. It was insprational throughout the past 3 years of my life, but I always missed on the chance to play it. Well, now that chance has come, and with updated Hi-Res graphics no less.
As for batman, that's a no-brainer, but I can't constrain myself to just 3 game of course. I might even deliberately miss out on Motorstorm just to get Batman, Y'know?
