My friend and I played a bunch! Every hour or so we would have a desync and it would crash / close the game.

I also vaguely remember having to buy land. We would try to build across opposite ends if the map from each other.

You could set up deals like selling power to the other player. Water when connected would just flow so you could steal the other players water, or set up a monthly payment deal for nothing in return (but really water).
