Wow, lots of fun for very few dollars! I paid aud$3 for it on the Oculus 1st anniversary sale. Probably $US2 elsewhere.
Plays great on my Rift cv1 and also very well with my Quest wireless with Virtual Desktop. Makes very good use of the Oculus touch controllers. You can also play it flatscreen as well.
I'd probably give it 3-4 stars compared to much more expensive Kart/racing sims but 5 stars because it costs about 1/10th the price of those, lol!https://www.oculus.com/experiences/rift/2467364466642773/
