Trackmania Turbo
Trackmania Turbo is strictly time trials. That means you're only racing ghosts and competing against yourself. If that sounds like something you like to do in your free time this game is for you. There 200 tracks and you can compete for gold or green medals in each of the challenges..
The licensed soundtrack is really nice and keeps the flow going betwen quick restart after quick restart. The music totally amplifies the addiction with this title, and I'm glad they display the trackname in the topleft corner each time.
And since the developers are so nice they added a free VR mode. It's absoluteing nauseating and awesome at the same time. A jaw-dropping experience for those brave enough to try it.
