Maybe next time you want a multiplayer game, DO NOT wait for an elder scrolls game. It's actually quite (read: ridiculously) easy to do. Hoping for a TES main game to have multiplayer is like hoping for your dad to get pregnant.

To be honest, I'm learning C++ right now so that when the game comes out I can get into modding and hopefully do something MP via Steam. It's a pipe dream, yes, but I do at least want to put forward some concepts since I really think MP could work extremely well.
Good luck. People spent years trying to do this on Oblivion and could barely do anything with it. If you get anywhere with it I will be happy to give it a shot, I just don't want it in by default.
