MTBFreerideVR, with support Oculus Rift and Razer Hydra soon.
UPDATE: RiftSuit will be simply a part of MTBF.
At this point I give it a solid 7. The game has the best look of any free game that I have ever seen and there is truly no other game like this for free. Yes the new update did bring some amazing new features(replays, leveling system, and racers to race against). However, I find that I come across a lot more bugs. Sometime I'll be going up a ramp or landing a simple jump and it will send me flying across the map. I felt like changing the map change the game and I'm not sure if that is a good thing or not. I would like to be able to play the other map but, this map gives me a whole new place to explore. Overall, This game has the potential to be an amazing game and I look forward to future updates.
