Best Game: Tie between Grandia III and FFIX
Worst Game: Godai Elemental Warrior
I had trouble getting into FFIX. I don't know why, maybe it was the art style or something, but I couldn't enjoy it the way I did FFVII.
Best: This is so hard to choose, so I'm going to have to give it a tie between Morrowind and Fire Emblem 7. I've spent more time playing those two games than anything else. I also really enjoyed the first Mass Effect, it had the best story of any game, but I've only played through once and haven't had any interest in playing it again.
Worst: Beast Wars for the PC or Cyborg Justice for the Sega Genesis. Soooo horrible.
