Number of users is something we can't share publicly.
Re V4V - Technically it is kind of V4V because our users generate value via AdRev and then we provide value back with prizes ;P. We believe good games stem from the pure joy of play. Adding in real-world value should just be icing on the cake. Not the sole reason people want to play (which I think it what is happening in the broader p2e ecosystem). To me V4V would require users to create value in the game, which is work, which strips the games of their intended reason - joy of play.
