We've been looking into creating a multiplayer game. We've made a few single player games, and there's not much that we haven't been able to figure out how to do. But how on earth does multiplayer work? There's a ton of documentation on Photon and we've gotten some simple things to work with it. But we're looking into P2P type multiplayer? We can't afford to keep servers running for a game that no one might play. Other Unity games like "The Forest" seem to have gotten this down, but where can we find documentation on how this sort of system works?
