Well, although I dont have an Xbox quite yet, but going to get one for Christmas, Im going to say the reasons I do want one (basically the same thing).
Different feel to the Controller. It seems uncomfortable at first.........but my hands never seem to get tired of holding it unlike a PS2 or Gamecube controller.
They know what they're doing online. I have a ****ty pc, but with Xbox I can play Half-life 2, Counterstrike, Ghost Recon, Fable, Halo 1 and 2 online (or at least soon) without worrying about specifications. Also, its rpetty convenient that you just pay £40 for one year,. A years an awful long time. Its not free, but you get a headset, countless amounts of online games in the shops, rankings and all sorts of **** ready.
Internal hard drive. I really did miss the N64's on cartridge feature. Xbox is as good as it gets at the minute.
Saving tracks to your Xbox. Nothing like blasting your way down a mountain designed by professional snowboarders, listening to your own albums.
they have pretty much every genre covered for me. Shootemups. Need I say anything? halo, solider of fortune, halflife 2 (soon), Operation flashpoint and a whole heap of games. Platformers, they wont beat Nintendo, but theres Blinx and Oddworlds oddysey. Adventure games, theres Morrowind, Fable and Star Wars KOTOR.
the reason Im getting an Xbox because nintendo's starting to piss me off. Zelda wasnt the greatest game to me, and metroid was ok. I just want a change.
