Today I bought Kingdom hearts RE: Chain of Memories for the PS2. I have a 80GB PS3 with partial backwards compatibility and it turns out that the game  freezes at the tutorial and is impassible.

I've decided to return it and add some extra money to get a new PS3 games so I was wondering if someone could reccomend me a good one.

Game I already have are: Metal Gear Solid 4, Little Big Planet and Uncharted.

Games I don't want are: Oblivion, fallout 3, Call of Duty World at war.

Valkyria Chronicles or Folklore.

Resistance 2, Motorstorm 2 , Valkyria chronicles, Naruto ultimate ninja storm.

Wowhawk, Dead Space, Bioshock, Ratchet FTOD

Resistance 2,Civilization:Revolution,or Bioshock.

I like Dynasty Warriors 6 though I doubt many others here do, and thus I guess you wouldn't like it either.

Ratchet & Clank: Tools of Destruction is pretty good.

GTA IV would otherwise be good but the camera sucks (it tries to follow behind the character and it tries to be free - yes, both of them; it doesn't stay where you'd want it to be yet it's too slow to say behind the character), and so does the shooting system. If you can overcome these problems, there's a good chance you'll love the game, though.

Super Stardust HD (a PSN game) is pretty good. You should try out the demo at least.

Gran Turismo 5: Prologue is pretty good, I've heard. Can't say much myself as I haven't played it.

I guess that's all I can say. I don't really have many games (I only have the ones you have, the others I mentioned I've only played unless I stated otherwise).

Resistance 2, Gran turismo 5, ratchet, THERE IS TO MUCH

Mirror's Edge, Prince of Persia, Resistance 2

@KylieDog

I forgot to mention that I already have PAIN sorry.

So I've narrowed my choices down to 3 games.

1.) Resistance 2
2.) Valkyria Chronicles
3.) Prince of Persia

The main reason i'm still undecided is because I love JRPGS because of their stories so that makes me want to get Valkyria Chronicles but I played the Demo and although I love it I seemed pretty bad at the game play. So i'm not sure if I wanna buy it.

Prince of Persia looks like it'll be a lot of fun and have a good story but its seems like itd be rather short with little to no replay value and I really dont want to pay full price for that.

Resistance 2 looks like it'll be lots of fun with lots of replay value because of the online mode and a decent story but it seems just like every other shooter out there.

So I guess you guys could convince me one of the three ways.

Valkyria Chronicles as of now
