I think the best PS3 titles are
1.Beyond: Two Souls
3.Uncharted: Drake’s Fortune
these three titles are the very reasons I decided to go the route of Sony over Microsoft, even though I really wanted to play Gears of War and Halo, but I haven't regretted even once.
I'm surprised nobody mentioned Heavy Rain! I really enjoyed that game. The atmosphere was fantastic, the graphics looked great and despite its antiquated hardware, the PS3 managed to run it flawlessly. I think that's the only PS3-exclusive game I've completed. I bought Uncharted 2 a couple of months ago but I've yet to play it.
I think my problem with Heavy Rain, much like Beyond: Two souls, was that it was for all intents and purposes an interactive movie that tried to sell the whole "your choice matters" even though it really didn't. I think there are lots of other games that did this better than Heavy Rain did. Even though I did enjoy it a ton I wouldn't put it anywhere near my top 3 Playstation exclusives. I think they probably are:I'm surprised nobody mentioned Heavy Rain! I really enjoyed that game.

I really need to find the time to play the God of War series. I have both the God of War collection and God of War III sealed sitting on my shelves collecting dust. I have such a backlog of games that I fear I will never get around to playing the God of War series.Agreeing with many other people here, the Infamous Games, Uncharted, God of War are all awesome. Metal Gear Solid 4 if you're a fan of the series, and the Ratchet and Clank games are always consistently fun.
