Totally depends on how satisfying the driving is at the end of the day. I don't think the procedural thing is enough on its own, heck, it may not even be a plus. I think a lot of people like racing real tracks. But if the driving is good, and the game gains the ability to randomly generate elevation and banking, then I'm more interested.
My thoughts exactly. I can only see this work if the driving and generated tracks are of good or rather great quality.
