FF 3 / 7 / 9 Zelda OOT Chrono Trigger was a fun game, but I was too young to care about the storyline much Definately Morrowind
Bioshock's was confusing since I didn't really pay attention to the guy talking. I just killed people.... But it was still the best with a good twist at the near end. Too bad I had already read stuff and they spoiled what happened in the end to me...
