If they were to ever do this, things like time of day, weather, terrain editor, etc would only be implemented on special maps, because they all have set time of days and weathers with textures and models made specificly for that. I would like a flat, grassy field, where u can edit the terrain add rocks trees etc... then do time of day and weather, i would love to make it rain at night, and make a building, and have ai weaponless flood come invade the building as you held them off.... zombies...
