Demos. Do not overlook the significance of demos. Many of the more hyped games have them. I recommend the Heavy Rain demo, personally. After you get it, be sure to give the game some attention. I know you're going to get a lot of lists but here's my short list of PS3 Must Play games--
Heavy Rain: Great graphics, great story, really compelling and immersing. Not quite like anything you've ever played before (aside from Indigo Prophecy). More movie than game but it really makes you feel like you're in control of what happens.
Valkyria Chronicles: One of the most charming games I've ever played. Once you get your squad the game becomes really addictive. A great strategy game that is fun to play, too. It's like Advance Wars mixed with a TPS.
Uncharted 2: Not as impressive as it was a couple of years ago, but still one of the best looking games you'll find this gen. It's the video game equivalent of a summer blockbuster. Nathan Drake's finest hour. Not as repetitive as part 1. Not as disjointed as part 3. It's a blast.
God of War 3: It's part of a trilogy so it would be wise to play the other two first. Still, the game stands alone and is, in my opinion, the best looking game this gen, at times. It's brutal and it has boobies.
