MMORPG/RTS/FPS Like the world is REALY REALY big or there could be about 4-5 Planets that you can go to and buy bricks rocks all that stuff and thats when you go into RTS and disign your Castle/City like that. OR what you could do is have this PvP System to where you have guilds and each guild has high ranks that can go into there HQ and disign it for PvP Arenas so its your disign VS. there disign. That game would kick ass!!! You MUST make it NAO!!!!
