Gran Turismo 5(GT5) features quite the robust course maker option. To get a better look at the creative process, check out this new video that popped up on YouTube recently. There are quite a few preset tracks to toy around with; you can set all sorts of parameters for each new track you make, and then you can head out and take a test spin. GT5 will be more customizable and more “free” than any entry in the past, and that fits right in line with this new generation.
