Jagged alliance 2. The king of turn-based tactical RPGs
Temple of Elemental Evil also.
Have you tried Knights of the Chalice ? http://www.heroicfantasygames.com/
It uses d&d 3.5, has turn based combat, good AI.. Supposedly a really good game. I played the demo a little and it def seemed pretty cool. Graphically, it reminded me of D&D Warriors of the Eternal Sun. It's def on my 'to play' list.
Currently doing a Gold Box run myself. D&D video games and turn based combat was made for each other. Don't know why they ever decided to go the RtwP route for BG/IWD/PST games. The combat would of been better if they were strictly turn based.
Hopefully Wasteland 2 is gonna have some good TB combat.
