Demos, lol. I downloaded demos ALL night last nighte --- queued up forza 2, dirt, and about a dozen others -- some in arcade. I'm using the play link instead of the microsoft wifi add on because I got one for 20 bucks and it is painfully simple to install. Only problem is downloads are slow. That said, I've got enough demos to keep me busy for DAYS if not WEEKS...
BTW, NinjaBee has a new RTS lite using bugs or something. I saw a post somewhere that looked like a must-buy.
