It seems there is no shortage of Tron inspired games for VR platforms. There is something about that look and vibe that just seems such a natural for VR. HoloBall seems as though it could have easily been a sport featured within the Tron universe. You even play against a snarky A.I. opponent in a quest to gain your freedom. A brand new car is waiting for the victor. The question is... "Do you even know how to drive ?"  Truth is, HoloBall is one of the best early pong/racket style games to come out for VR platforms. TreeFortress games has done a great job of delivering a game that will not only entertain you to a very high degree, but it might also help you burn a few calories in the process. It's a helluva lot cheaper than a health club membership.
