I bought The Temple of Elemental Evil back in the day, but I gave up on it. I don't remember the exact technical issues, but I DO remember the absolute worst voice acting I've ever heard.

I also remember a bizarre moment when my paladin made romantic advances towards a village woman. She was an adult, unmarried, not evil, and reacted positively, and yet this caused the paladin to fall. I don't know if this game was made by some ultra-puritan or if someone got D&D paladins confused with Catholic monks, but I do know that it was one of the final straws for me.
