Yeah... but the difference is with skyrim you have the entire team focuses on the single player game just in different teams focused on different sections. In a multiplayer online game you have multiple teams working on different procjects that don't ever interact with any other aspect of the game but still have to take up space. ie: the crucible and crucible gametypes damage raitos etc. In a game like skyrim, every single person is working on something that effects the story of the single player game, because thats all it is. I would love to go into numbers of how big the companies are and how many people per team etc, but I am at work and have a meeting for the next few hours so that isn't somethign I can do this second.
