Was a two way battle between God of War and Uncharted (with Honorable Mention for Heavy Rain). I'm gonna give it to God of War.
God of War was good but kinda boring. They kicked things up to the next level with God of War 2. Finally, God of War 3 was a mind-blowing experience. The series started good and kept getting better.
Uncharted started out good but kind of repetitive. Things got kicked to the next level with the highly polished Uncharted 2. I was a little disappointed by Uncharted 3 and its disappointing story. The series seems to have peaked with U2.
Heavy Rain would have made the list if there were more titles in the series. As for the rest of the Sony franchises (inFamous, Twisted Metal, Ratchet and Clank, etc.), I don't really have any feelings for them one way or the other.
