The vast majority of games that work with the HTC Vive and Oculus Rift will also work with Windows Mixed-Reality headsets. So you can always check the overall lists for the best VR games period. This list, is specifically ranking the games that are available on the Windows Store for the Mixed-Reality platform. These games are 100 percent native to the Mixed-Reality platform, so you know they've been tested and approved by Microsoft to work with any of the various MR headsets. Microsoft has still been somewhat slow in getting more developers to port truly native versions of their games to the Windows MR platform. Hopefully this will improve dramatically in the very near future.
