That gap of 10 years is a little disheartening.
So many great games not mentioned.
Witcher (2007) IMO redined a dying RPG genre.
Arx Fatlis (2002) a tremendously well designed RPG that stands up to the best of them.
Planescape (1999) had one of the more unique stories of any RPG.
Realms of Arkania (1994) with one of the most comprehensive stats system of any RPG to date.
System Shock (1994), while not a classic RPG, combined the action of a FPS, with a deep role-playing experience. SS2 was one of the greatest RPG hybrids ever released.
Magic Candle (1989) probably one of the best RPG's ever made.
Faery Tale Adventure (1988)
Who can forget the slew of SSI spin-offs: Al Quadim, Ravenloft, darksun, Thnunderscape, Menzoberranzan. None of these would make my best of list, but they all bring back great memories.
