Temple of Elemental Evil 2, Planescape 2 (the least likely, sadly..) - would absolutely love those dnd games to receive proper sequels.
Nice game when on the Surface, but once you began dungeon crawling - soooo BORING!
I loved the "pie" used for spellcasting (actions in general?) .
I was still new to DnD back in 2003, and the dungeon crawl through the temple for the first time was one of the most thrilling experiences... out of resources, near death party, scouting for those hidden doors to try and get the f*** out of that hellish maze and rest...only to find an undead prince, who gives you the most OP weapon in the game for saving him. Damn, ToEE hit me hard then, I'm still replaying it every couple of years. Graphics still hold up and music is amazing. Solasta is a good effort, but pales in comparison.
