Without any knowledge of downloads/purchases it’s really hard to tell. The best i’m going with right now is the star ratings. Now granted the number of people rating something vs the number of people actually playing is extremely one sided but never the less the ratings are in the 1,000-4,000 range. But then again no one is using rating conning methods on the Oculus market so it wouldn’t be fair to compare it to anything on the play store, plus there is the fact that your audience is limited to select phone users which us further limited to people who have the phone and the HMD.
