Like mods for example.. Half-Life 2 is going to suck bad on Xbox because there will be no mods for it and no way of making expansions/modz
And all FPS's on Consoles are only a fraction as good as they are on computers as those who play counterstrike know.
So the Counterstrike on Xbox is going to suck much worse then on computer because you really can't do as much online and such as you can on the good ol' computer.
Also the xbox hinders games so much its pathetic really.
Though Halo is fun on Xbox it is atleast 4x better on computer without the autoaim that ruins the fun of aiming, and with a faster mouse and keyboard against the slow controller. Also you get new stuff tahts really fun(flamethrower for example)
Xbox live is just a joke really. You pay every month for hindered online play. The reason THUG and all of these online games didn't go to Xbox is because Microsoft is extremely picky at what goes through the internet so that slows the piss down out of the game. Microsuck actually monitors every bit of info that goes through Xbox live. And the lil' Xbox hard drive is just horrible take it against my 100 gig computer hard drive and see wut happens. Xbox is great for what it is made for, but computers can do that and more so why bother with it really.
Also most games that even come out on Xbox come out on PC anyways.
