I picked up 3 games at the time I bought my 360. Call of Duty 2, Sonic the Hedgehog....and can't seem to remember the 3rd. Might have been the madden from that year since I was playing it a lot on the original Xbox. First game ever was pong!
Shortly after, I picked up Rainbow Six Vegas and that is why I am now a console shooter player...played that game non-stop until COD 4 was released a year later.
