I once played this game Project Earth, that was a space RTS. In its gameplay it was pretty standard space RTS, but it had quite a few missions where you didn't simply fight on 1 map. You had to fight on 2 or 3 maps at the same time in some missions. There was no way of transferring units between the maps. Each one of those "threads" was like its own match. One could switch between maps with F1, F2, F3, F4, F5 respectively. It did definately freshen up the normal gameplay for me.
