Question: is there not a version of Temple of Elemental Evil for NeverWinter Nights in the form of a module? I am sure I saw one somewhere, and from what I heard (of course, I could be mistaken and this was all for Diablo) that it played far better than the original. I would have to go and look that up in order to be certain, though.

Not if it had NWN's far inferior combat engine it didn't :D

(Granted, I haven't touched NWN since mid 2002 when it came out, and it certainly was stable, but apples and oranges comparison there. If you like D&D combat, NWN is a poor substitute, because there's not a lot of story to work with)
