What PS3 game should I get that would look awesome on a projector?

I'm about to set up a home theatre with a projector and 92" screen. My primary source will be a PS3 - mostly for BluRay movies, but I'd like to pick up a new game also that would kick ass on that screen. I'm not a big gamer, but I'm willing to take suggestions for a game that will really suck me in. I tend to like racing games (like Gran Turismo) and sport sims, but I'm willing to try something different.

So, any suggestions would be great, thanks!
