Pre-ordered, got the code, and was trying my hardest to figure out the game. Haven't played a game like this in a long time I was really hoping for at least 1 or 2 single play scenarios and a tutorial level of sorts.
Probably not going to have the money for the game come the time it's out, so I went over to Gamestop's website to cancel my order, and they've added "Order cannot be cancelled once a beta code has been received" to it's page. Notice the typo there, I copy/pasted that from the site.
So now I'm going to have to get the game and sell it to someone who actually wants it.
