Ok, this is a great start. But it can be way better. Since this is a launch style game, the upgrades are a big part of this, and they should be more in depth. Gauges are also needed.
Information is the key! Instructions would be nice. The GPS controller is alright, but it should be an actually GPS, and have a radar on the HUD when it's purchased.
Overall it's an awesome start. I can't wait to see more.
