Holy crap, that reason alone is enough for me to buy it. I don't like skating games too much, but they are fairly entertaining. And for less than $20, why the hell not?
The 2nd and 3rd Pro Skater games were my favorite. I actually played Pro Skater 3 a couple months ago, boy those graphics... but I am excited to see how well the "HD"fying goes, if it works out. I loved making custom skate parks, hope that's still in there.
