This might sound stupid but can't they add keyboard and mouse support to Xbox One? Then make it so that if you want to play the rts you have to use it. Also add this for all games. (not the necessary key board and mouse part, just support) then when you play multi-player it sets it up so that you only go controllers versus controllers or m&k versus m&k
