Getting a PS3…

OK, so longtime readers know that I've been a faithful XBox guy for years now, but really I'm running out of games (awesome sale this past week aside) and there's some Sony exclusive stuff that I haven't gotten to play since I had a PS2.  So I bit the bullet and bought a refurbed 160GB PS3 off Ebay this weekend, which means I don't need to renew my XBox Live membership to keep using Netflix in a few months.  

So any recommendations of PS-exclusive stuff I should be looking out for?   God of War is the primary reason I'm getting it, but I also want the Ratchet & Clank games and re-releases, and probably the Sly Cooper collection too.  I hear Uncharted is also pretty great.  What else should I be looking for, keeping in mind that generally anything awesome that's multi-system I've already played on Xbox.  Bonus points if it's cheap.
