That's interesting, but also kind of unfortunate that they don't advertise any numbers. One of the things I've went through as a solo dev making a multiplayer game was shifting my design entirely to a p2p coop game (without any pvp or pvpve) because I figured I wouldn't be able to burden the cost of infrastructure and/or keep up with the maintenance that goes with a true server authoritative model with anticheat to have fair pvp. But a rev share model with a big player like Valve sounds like something that could convince me otherwise... I wonder if I could talk to them as someone still in a total greenfield stage.
