I would love to see changing weather patterns that would actively affect not only the map but the way a game would be played out by both bots and yourself. An example of this could be the effects of industrialisation eg: deforestation, soil degradation and influencing more dangerous water patterns like tsunamis, earthquakes and many more. Adding this as an in-game mechanic in harder modes of the game or perhaps as a custom game mode/feature would be an amazing addition to the teams game.
