Finally finished up God of War II myself. Had to play through the game a second time to get the 3 secret chests since I missed them all. I think the challenge of the titans was overall easier than the first game's challenge of the gods. Did have a little bit of trouble not taking any damage on challenge 7 though.
I finally have a backlog of games so I'm not sure what I'm going to play next: Dragon Age Origins, Demons Souls, Borderlands, Fallout 3 Game of the Year or Darksiders. Darksiders is from gamefly so I'll probably play that first.
Future DLC backlog is building up too: Assassins Creed 2, Resident Evil 5, and already tons of DLC for Borderlands & Dragon Age Origins, plus the Dragon Age retail expansion called Awakening.
Then through April 2010: Army of Two the 40th day (demo sold me), Dantes Inferno, Bioshock 2, Heavy Rain, Battlefield: Bad Company 2, Final Fantasy XIII, God of War III, Red Dead Redemption... where am I going to find the time to do anything else?!
Edit: Also pretty excited for: Dead Rising 2, Dead Space 2, and Dead.... errrr I mean Fallout New Vegas later this year. And the next Twisted Metal game! I think that will be announced at E3 2010.
