Why buy Microsoft`s XBOX 360?

Well, the first reason would be the fact that the Xbox 360 is on the market for more than an year and there are plenty consoles out there.
The Xbox 360 comes in two versions:a stripped out version Xbox 360 Core System and the Xbox 360 Premium that includes all the accesories from the Core System but also adds a 20G Hard Drive and a wireless controller. Both versions are able to play DVD or HD DVD media(if you have a HD DVD player), and the console is powerfull enough to display everything on a High Definition TV.
Accesories available for the console include an universal remote control, a HD DVD pleyer, wireless headsets and the vision webcam. For more info try this review.
Also Microsoft has a very good network for players around the world called Xbox Live where you can play games, enter tournaments or buy more games.
But the most important thing when buying the console is what you can play on it. So here is a list of Xbox 360 Games:

Gears Of War

Elder Scrolls IV : Oblivion

Need for Speed Carbon

Halo 3

F.E.A.R. First Encounter Assault Recon

Tom Clancy's Rainbow Six Vegas
