The online games that I have played have no where near the depth of a Wizardry. For that matter, even other single player RPGs usually don't come close.With all the problems associated with PC development (having to try to support different Operating Systems/Platforms, Graphics Cards, Sound Cards, etc.) ... I would not be surpised if the next great RPG came out on the console (which can be multi-player, since they can connect to the 'net).
