I've got to say that I'm really enjoying the demo too (fp subscriber)... for all you technical types who get tired of the PC getting wonder victories or maybe want to try the Assassin Mode or other option in the demo then you may want to look at the file autostart.ini.
The game just gets better and better. You really have to use the market to get an edge, the battles are great.. I can't wait to get the proper edition because I hear the background music is great (demo doesnae have any). It adds quite a bit to the traditional mix while not anything ground breaking, it's just polish. It plays great, feels great and is fun. I'm definitely buying this one on day one. Just playing against the PC shows already what great promise it's MP will have.
