Don't forget that BK was released in a 2 disc pack with Viva Pinata as a 360 console bundle and can be found for $10-15. Both games and manuals are original discs, only the case is shared.
There's two games that really get overlooked by the "hardcore" crowd. Viva Pinata is a fantastic game, and Banjo is a pretty good vehicle building platformer. I have spent way to much time playing Viva Pinata in the past though.
