Excuse me, why haven't we met before? Xenogears forever! I still have my game to this day. I even made a suck ass story about Abel and a guide book about characters, places, etc.
Xenogears, all day long. No contest. Best story line in gaming history.
Some honorable mentions would be SaGa Frontier, FF7, really any FF before 9, when they went to complete and utter shit.
EDIT: Also, Fallout is a shooter with RPG elements. You kids have no idea what a real RPG is.
