FPS + RTS. Thats SAVAGE and SAVAGE 2. its a multilayer game on where one player is the general in the sky. and the others are fighting in the ground. just like that omnigame idea (in a much lesser scale) in Savage whatever the General do affects directly and in real time the actions of other players. You can even play as Builder to help build barracks etc ... a la Age of empires and then accesses more units . etc. Ben if you have some spare time check this game.
"Here's my proposal. Start with the standard RTS model - two players directly controlling two warring armies of units across a massive battlefield. But also spawning on the map is a third group. Mercenaries, individual warriors controlled by human players"
YOU NEED TO CHECK SAVAGE 2 ASAP THAT HAS ALREADY BEEN DONE.
