Topic: Free Terraforming
I was reluctant at first to suggest this, due to the NIC sink lost by removing the charges.
But I think now gamma terraforming being so much less OP and almost useless to block TPs and also the amount of time it takes to terraform manually, depriving yourself to earn NIC whilst carving the world. Also it seems a waste if degradable over time if not near your OP.
For the NIC sink I would suggest a fee for land for it to remain without 'erosion'.
Advantages would be free to experiment, and far less headaches and costs for mistakes. Any balancing change done in the future will not need refunds. Ultimately does not cap creativity.
