I prototyped a game in unity which uses the HLAPI lobby system. I could host a game and invite friends to join my game by giving them my IP), but it remained hosted on my computer. single player or couch co-op games just started a local host using the same code. does playfab allow me to work this way? or can I use parts of it for matchmaking only? I don't want to go too deep into it to find out its not really what its for. end goal is for it to work the same way but be able to invite/join xbox friends games.
