You all know the story. But the Xbox made its name by appealing to the classic gaming audience who love shooters, driving and sports games. And it has done it superbly - if you like traditional videogames the 360 is still the best there is.
The struggle to create a universally accessible game seems to be a problem for the 360. Look at Xbox Live. It's a great, by far the best online service on a console. Sign up and you get access to a stack of casual games like Zuma, Bejewelled, Hexic and the rest. But considering that you have to buy a 360 and then pay £40 per year for the service you can see why the casual audience could be put off.
