Well...what else is there to say?
I bought 3 games to get started:
Rachet and Clank Future: Tools of Destruction
Heavenly Sword
Dead or Alive 5
So far, the controller layout (and the small triggers) has been less of an issue than I thought, the thumbsticks may actually be better. I even downloaded motorstorm and COD:MW 2 demos to get a feel for the thumbstick-centric controls.
