Hello everyone! Today I have finished the Terraforming Mars mission, and am releasing it in the 0.13 beta. It can be obtained by forming the Martian Federation, and will require you to build a number of expensive projects on Mars in order to produce a breathable atmosphere, water ecosystem, and biosphere.
When Terraformed, Mars will take on an Earth-like appearance, and gain a number of useful deposits in all of its regions, including surface water and oxygen, both of which are very useful for building a powerful empire. (The regions that are "flooded" by the terraforming process will not receive negative affects, but may have some small downsides in future)
This process must be completed in phases, and requires some advanced technology before being accomplishable, however it is very rewarding, as it will decrease project upkeep (Oxygen Atmosphere) by ~15%, spawn many useful deposits, and increase Mars' carrying capacity by 50%, (as well as any incidental bonuses from the habitability increasing from 60% to 90%).
Economy Changes
I noticed the pacing for space nations had been damaged by the removal of strategic resources, and so in order to achieve more parity with the previous system, all resource capacities now give a little bit of money when produced. This value is low for high-population countries, but very useful for smaller space-based countries. Ideally, the pacing should now be on-par with 0.12 for these countries, but I am not 100% sure.
