Thank you for explaining. > there's big advantages to having a deterministic simulation and relaying the player's commands instead of the whole game state, in fact unless you know everyone playing the game has a very good internet connection it's the only viable option. If I understand, running it all on a server and just updating player UIs doesn't work for an RTS because some user Internet connections bottleneck the updates, putting those users at a disadvantage. You need to keep as much on the client as possible.
