its xbox 360, its violent and its HILARIOUS! I'm sure the other games on the disc are great… HL2, team fortress etc but i am totally addicted to PORTAL! its incredible! not very often you get a game that can make you dizzy and scared of being vaporized and make you laugh all at the same time! heck i probably would have paid $119.99 just for PORTAL and all its wonderful little suprises, like the “companion cube” and “still alive” song =) 10 out of 10! XD
