Not worh buying an Xbox BY FAR.
Save up and get a gaming PC, PC games are WAY more fun because of the mouse and keyboard, and alot of PC games are freakin' unbeleavible! (Some of you will understand that.) Like TF2, CSS, Half life, The mods for Call of duty games (exempting MW2) and many other great games. Plus the PC community is much more mature. (well, they are easier to find, we have lots of immature kids =D But they are amusing immature.)
