Power Drive Rally is one of the most exciting and addictive easy-to-learn/hard-to-master games that you can play, especially if you intend to play it with friends.
BlazeRush is a really fun isometric arcade racing experience that manages to deliver explosive action, imaginative weapons, and balanced speed boosts to create an addictive flow.
On your journey you will encounter other people on the road - all potentially worthy companions to crew up with, or future rivals to compete against.
