I loved the hell out of the first one. After that I remember they tried to go "darker" and I wasn't feeling it. Still though, I'd consider getting this one for nostalgia's sake and I'm sure the Trophies would be fairly easy.
Words...cannot express how insanely excited I am for this. I was a kid when the first Jak and Daxter came out, so it's always the "first game" I remember playing. Then Jak 2 and 3 only added on to this. Day 1 purchase for me!
