Wizardry 6 or 7? (Since you like Wiz 8, the previous games should be up your alley too)
Any of the Infinity engine games (BG 1+2, IWD 1+2, Torment.)
Ultima's 4-8 (A must play really)
Temple of Elemental Evil (Great turn based combat like Wiz8 yet quite short.)
Stonekeep (A first person classic RPG from Interplay, which was a bit of a sleeper hit. I finished it twice, I enjoyed it so much the first time.)
