New PS3 owner looking for good games

So I recently acquired a PS3, whose primary use is a Blu-ray player for my new TV, and a Cell programming experimentation box. But of course, I also want to play games for it, so my question to you guys is, what games do you recommend? I already have the following:

Super Stardust HD (kickass game, too)
Gran Turismo 5 Prologue (I know I complained about it, but I plan to trade it in after I've finished all the events)
Ratchet and Clank
Burnout Paradise (girlfriend wanted this one)

For reference, the only PS2 games I owned were Gran Turismo 3&4, R-Type Final, Gradius V, and Guitar Hero 1&2. I also have a pretty powerful PC, so no FPS games unless there's no PC version.

 Is this because you didn't liked any other game?  If that is true I have to agree with DmeisterJ about your taste;
