With the creation of Cliffs and the explosives to remove them, could we not make these Geoshaping Charges instead and add an alternate use for them that if they are used at a shoreline, they create a 3x3 area of water? This could allow players to reshape terrain including water, which as far as I'm aware is the only kind of alteration not yet available to players.
Could be handy if you could create a canal or two to your power plant.
yup would throw game balance out of wack. everyone would be building islands with a single choke point.
[edit]if you really want it, there is a mod called Waterbomb.
