If you're reading this tonight (1st Dec) then it's not quite happened yet but XBox 360 launches in the UK tomorrow (2nd Dec) as you may be aware. I've been able to play a couple of pre-release games this week and can report that they're fantastic. Of course I would say that being a Microsoft employee but any of you who've met me will know that I tend to speak my mind and don't just push MSFT products.
The graphics and game play of Project Gotham Racing 3 and Call of Duty 2 IMHO are fantastic.
....and before anyone gets the wrong idea I don't have my own XBox 360 yet nor do I get a free or discounted machine - I have to queue up like everyone else!
