Nice! These are great ideas, but you've somewhat jumped the gun. There is also value in not lowering blockchain traffic. There isn't a lot users can do here at the moment. Users need something to spend RCs on. It's more useful to force players to pay to play using resource credits rather than host a dedicated server.

Also, if you are trusting a third party server this isn't secure. The server can lie and there is no way of knowing if a player made a certain move or not. At this point you'd have to use second layer scaling solutions where players were signing transactions with their private keys off chain. This extra layer of complication isn't something that should be worked on unless the game actually went viral.
