Need some suggestions!

So I just bought an slim and I already own a PS3. I want to find the 'exclusive' gems in the marketplace but I really can't think of or find any that haven't jumped over to the PSN Store as well as the marketplace. Can anyone point me in the right direction? Thanks in advance. :)

EDIT: 1.) Price isn't really an issue 2.) I enjoy playing almost any and every game, so any suggestion is welcome. I am not very good at puzzle games though, but that's it.

Shadow Complex, Super Meat Boy, 'Splosion Man, Ms. 'Splosion Man, Bastion, Perfect Dark, Toy Soldiers and Toy Soldiers cold war, Banjo Kazooie and Banjo Tooie, Trials HD, and Insanely Twisted Shadow Planet are some that come to mind.

I've heard Shadow Complex is pretty good. And are the Banjo games just HD remakes of the N64 games?
