I am a proud owner of a XBOX 360 and a PS3. I like to play games on both my consoles but with a lot of gamers preferring the XBOX, i have shifted a little bit of my attention away from my PS3.
Buying original games from stores is pretty hard on everybodys' wallet and purse. But there are ways and means of hacking your XBOX so that you can download games from the internet; write the games to a DVD and then play them on your XBOX.
While the PS3 does not have a hack as of yet(so they say), there are ways and means of doing that with your XBOX.
