IGN has posted their NBA 2K13 preview discussing some of the new additions to the game, including The Shoe Creator.
Visual Concepts spent perhaps the most amount of time during my demo showing me their craziest feature yet: the Shoe Creator. Yes, they've had a basic version of this before, but the ends of the earth they've gone to on this smack of a studio that clearly has no competition to worry about and is free to pursue flights of fancy like this (again, I mean that in a nice way!). 2K13's Shoe Creator is, essentially, the virtual shoe equivalent of Forza Motorsport 4's livery system. Except in that game, you can't click a button when you're done and order the car you just designed, complete with that custom paint job.
Yes, you can build your own kicks using different materials, colors, patterns, and more. Dozens of layers (45 of them, to be exact) let you highlight every detail you like. You can then upload those to the web, where other users can rate them. Want to go a step farther? Get this: the game syncs with the NikeID website and you can actually have your virtual shoe made real and shipped to your door. Perhaps Visual Concepts will let us try out that particular feature next time...
