What delay would the lockstep net turn have to be increased to to allow 32 players like FPS? Usually it's 200 ms, so if it's 1 sec, could it support 8 * 5 = 40 players?
How could casual drop-in be supported? I see two ways: downloading the whole game state, and a few catch-up net turn packets that happen while downloading, or sending all the net turn packets since the game started.
What will cross-platform multiplayer RTS games be like when you can play between smartphones and computers? And drop-in any time like in FPS games? For the drop-in mechanic, I was thinking you would be a business/empire that starts off with a certain amount of money and when you leave the game all your property is auctioned off. It wouldn't be very comfortable to play on a bus but I can imagine lying in bed and playing it on a smartphone.
