Let me think...
Valkyrie Profile - Playstation - for it's greatness and originality.
Xenogears - Playstation - for being the best jRPG ever and its 'epicness'.
Baldur's Gate II - PC - for great storyline and the use of D&D 2.0 system.
Even though FF 7 was good, especially the beginning part in Midgard, in my opinon it was greatly overrated. It's nowhere near Valkyrie Profile or especially Xenogears. And to the person who mentioned Diablo II - it's not an RPG, it's a hack & slash.
