I think that it would be a much better idea to keep the game small and let a max of about 6 players into the game... if even that many. There are lots of issues that come up such as... how will you rest? how will mods work? custom textures? will the story be as good as it usually is or what it have to be "TES-Lite" in order to keep the action-based multiplayer atmosphere alive. The problem with adding in tons of players at one time is the fact that it becomes a competition then and no one wants to create a "gimp" character. Bethesda would be forced to keep people within certain character class limits and prevent the custom creation of a class. TES has never been about balanced characters and that is what would have to happen if they made an Action-RPG style game with multiple players (think Diablo 2 or Silverfall) or an MMO (think WoW or EQ2). An MMO would KILL this series. I love the fact that i can escape all the idiots in my WoW guild be playing a bit of single player RPGs. I hope to the Lord that BethSoft doesn't sell out and go the MMO route.
