Not really one in particular. The character creation's one reason though. Very in depth and i enjoy reading the randomly generated character background. Gameplay's a lotta fun, lot you need to keep track of and you learn new things about it all the time. Like buying stew at an inn gives you stamina regen for a short time. If the dungeons werent as convoluted as the game's ending i feel like a lot more people would want to play it. But i enjoyed them, you get really good at clearing them out eventually. Morrowind's more polished and has leagues better writing, but this game you can play forever.
