It's My Birthday! What Should I Buy?

Ok guys, my b-day was the 8th of June, I had preordered the game Prototype but after seeing some recent reviews for it, I'm wondering if I should get another game. What I had gathered from the reviews/previews is that Prototype gets old fast, and nearly everyone mentions inFamous in their commenting on Prototype. This is not a inFamous vs Prototype debate, actually this could be ANY game. The games I have already are quite outdated and for the PS3 so pretty much any suggestion for a good game will do. I already have Warhawk, Little Big Planet, Rock Band 2, Oblivion, Saints Row 2, Battlefield Bad Company, Fallout 3, Resistance 2, Army of Two, Metal Gear Solid 4, Skate 2, Assassin's Creed, and Turok. I WOULD REALLY like to get a great game with outstanding gameplay and I don't want to feel that horrible feeling of wasting fifty of my hard earned bucks on a cruddy game. What should I get?! I played the inFamous demo, it was pretty good, the only complaint I have is that once you have killed someone, they don't turn into a ragdoll, more like a frozen state on the ground. Other than that guys, I don't want to waste my money, any genre really, has to be for PS3.

It would be great to respond ASAP cause you know, it is the 10th...

I know its an old game, but I didn't see Uncharted on your list. I would definitely get that seeing as the second one is coming out here in the next few months. It's short, but it has a ton of replay value. Great game!

^ He's right, you can never go wrong with games like uncharted.

If the no rag doll effects are your only complaints, you should probably get inFamous :)
