Yeah whats the thought process here???
The only real reason I could see them wanting to release a demo is to see how there servers are going to be when a thousand people jump on it to download it at once. It seems to me that they like to make sure things work correctly, which isnt a bad thing. But I dont get the logic in releasing a demo to an add-on when most people that will buy FC already know what they are getting. Its not like you can have FC as a stand alone game, at least I didnt think so.
Anyways its good to see some progress being made but I hope this demo thing isnt a way to delay the final product longer. Maybe they will release both demo and full version at the same time so you can try it before you buy it?
