I thought about posting this in the video game topic, but I thought maybe to get the info out to everyone here, its own topic would be better.
The people at Kotaku (a nice go to gaming source) thinks Best Buy messed up---It's supposed to be a promotion tied to video card purchases, not standalone evidently. I've vaguely heard of this game, and decided to purchase it since I think it will be worth 1 cent. Metacritic gives it an 82 / 100 and Gamespot gives it a 9.0 out of 10.

You'll have to signup a bestbuy account if you don't have one already. Worth a shot to see if they honor it, or just cancel it.
