Mind you, this is the same world (Greyhawk) that has places with names like Verbobonc and The Pomarj.
Still, it's fun going through this as a player, even if it is a computer version and not a paper-and-pencil version, just because Temple of Elemental Evil is almost "definitive" Dungeons and Dragons, and I never expected to actually get to play it. Written by ol' E.G.G. himself, it has a somewhat more subtle sword-and-sorcery flavor than the flowery history and intricate social structures of Forgotten Realms. This is oldschool D&D, where you get swallowed whole by giant frogs, and if you don't lose at least one party member per encounter, the DM thinks the dungeon isn't tough enough.
It's fun -- but it does get frustrating to have to keep reloading save games and fight the same battles over and over again. ;P
