hey this is grins' son, 18
as far as games that he would like i would sugest guitar hero 3, its out for ps2, ps3, Wii, and xbox 360, and rock band has a 360 version as well.
as for a different game, i would sugest forza 2, if hes into exotic cars and racing then this is a great game, complateley realisic looking with car custumization in mind, has eveything from everyday cars to cars like ferrari and lambrogini, to formula 1.
o and about the post above mentioning the guitar i would stay away from the walmart and target brands (known as First Act) as you tend to get what you pay for, i have a cousin whos fretboard is pealing of the neck (very bad) , and go for a local music store and buy a starter pack from ibanez or fender (fender calls it the squire Phat strat pack), they tend to cost more ($250 instead of $150) but are way better made and come with decent equip for a starter, althought i would buy a new cable right away as you can get decent ones for like 10 dollars as the original cables tend to create a lot of background hum and white noise, this and a tabature book of his favorite band would be a great idea
