Correct!
One thing I'm still debating with myself is to whether or not flip the terrains used for Swamp and Jungle on Mars (Basin Ejecta and Terraformed respectively), so to use GW to terraform Mars, like what is already done for Pluto. My original intention when I first converted this scenario from MGE was to have lots of cities to conquer late in the game, but GW on Mars with the current terrain sorting completely kills the colonies, since Basin Ejecta has zero food production. However, I did make this scenario as part of a storyline about the Plutonian Empire, and what I have as canon for it on another gaming site, which is that Mars isn't actually terraformed for at least another few thousand years, while the other Earthlings are exiled to Belle Terre for those years. So my choice is to either preserve the canon part of my story, or make an exception for the sake of gameplay, and make GW terraform Mars.
Granted I could create batch files for switching between storyline modes (In this case, simply flip flopping the Terraformed and Basin Ejecta terrains to the end user's preferences), although that's still beyond my skill set for the time being.
Had TNO been able to allow suppression of GW for either specific maps or all maps, My intention would have been to suppress it for Earth and Belle Terre (the alien Earth). That was so I could manually drive GW with Events on Earth, and prevent it entirely on Belle Terre. For the next version that I upload, I'll include a secondary events.txt that doesn't include the end result of Earth being uninhabitable, as I would prefer to try to give players some choices in how the scenario plays out, to hopefully reduce repetitiveness (and have still more cities to conquer too!
). The batch files will be included in a much later version for sure.
As for the Engineers, there are four such types, the ones from the Original game, Geo-engineers which has the Engineers flag, Plutonians, which has the Engineers flag, and a "hacked" Boeing airplane also with the Engineers flag. They can all use O to transform, but with ToTPP, I have made it so that certain terrain types can not be transformed until someone discovers Terraforming. The difference between these units is that Geo-Engineers and the Boeing plane can build spaceports, but Engineers and Plutonians can not. When the Plutonian Empire acquires Mars Colonization, they'll be able to build Geo-Engineers alongside Plutonians. This is mainly so Plutonians can be automated with K, without having to worry about them building spaceports in unexpected areas and letting an enemy unit sneak into your territory.
