Terraforming with a twist: seems a nice balance way to make it hugely more interesting, is to have terraforming not cost anything in terms of NIC, just a time sink.

Seems a tad unrealistic that dirt/sand comes out of no where so; the terraforming module sucks out dirt, to lower tiles. And to raise just need dirt which need to be transported to the location needed. Simple use of scarabs and field containers. Can kind of balance it's self out as you can't use more dirt than is available on that island.

So how would you like shuffling dirt around at no NIC cost?
