I am a complete newbie, looking into playfab for ue4, but, nothing makes sense in pricing. What is a compute hour? Why is it listed only in the free version? What is are PlayStream Event, Telemetry event, Profile, Content and config, Cloudscript, Insights, and Party? I am only looking for getting data from client to client cheaply and efficiently with a simple matchmaking and party system, and have read the documentation already, however, I still do not understand it, or what is required/most efficient for my project, in this case, a simple fps game, mostly to test out how this all works.
