I just finished playing through the demo for xbox 360, and its awesome. Of all the skate games I've played, this is the only one that gives me the same feeling as when Im actually skating in real life. Every trick depends on how you flick the toggle sticks, how fast, what angle, what pattern, etc. Not only that but the patterns are all correct, it mimics how you'd move your foot to make the board to the trick perfectly.
It comes out September 2007, I seriously recommend getting it or at least checking out the demo. Tony hawks is definitely out of the picture now, I dont see Proving Grounds doing nearly as good as Project 8 did now that this is out.
Not to mention the graphics are insane, the sound effects are exact, and there's a huge area to skate and explore. Plus the live feature lets you skate online with others, or you can even record footy of you skating, then edit the footy with a built in movie editor, and upload it to the net, where you can hot link it to things like facebook, and if Transworld (one of the biggest skate mags) likes it, they'll feature it on their site / in their mag...
Its also pretty sick that my friend's cousin (Chris Cole, a major pro skater) is in it
.
Anyways... back to playing the demo.
