1. Star Wars: Knights of the Old Republic
2. Final Fantasy VI
3. Mass Effect 3
4. Fallout 3
4.FFIII (SNES USA)
5.FFIX (I really enjoyed this one for some reason)
Some people think Earthbound is overrated but I find Mother to be the by far the most enjoyable RPG series due to the funny quirkiness with some incredibly sad/dark elements mixed into the story.
