I won my Xbox 360 through the "win every hour" contest they had going at the time. Lots of GAF people won it, since if you played your cards right, you could have a 1-3% chance of winning every day by collecting enough free-to-enter tokens. After about 15 tries, I got the 360 for free.
The system came a week early, all part of the "play it before you can buy it" promotion. They actually wanted you to throw a party to celebrate the system's arrival. It came with 360 coasters, coupons for free pop and chips, buttons and probably more stuff I'm forgetting. Problem was, it only came with Kameo (you ended up getting Need for Speed later on). Remember Kameo? Since you got the system early, its not like you couldn't pick up any more games or anything.
So yeah, they expected us to throw a party for Kameo...
