Ultima Online 2
Sid Meier's Alpha Centauri 2
A sequel to Planescape:Torment (Maybe focusing on how the nameless one's first incarnation mapped the hells that eventually led the baatezu and tanaari to discover each other (his big crime), sparking the blood wars, or maybe we play as his other incarnations? Or screw the nameless one altogether and play something completely different set in the planescape universe?)
