The problem i had yesterday was that soil enhancement didnt appear on the list, after i used it once.
When i placed it the first time i had a choice of 3 tiles to place it on, so i thought i would be able to do it 2 more times after the first. But it never reapperaed on the list.
Many of the terraforming projects can only be used once per planet. It would likely be beneficial for the developers to communicate this more clearly to the players. It would also be beneficial for the terraforming projects to be revised, since under the current model there are some repeatable terraforming projects and some one-per-planet terraforming projects, and the one-per-planet terraforming projects can, if I'm not mistaken, be wasted on tiles which could be terraformed with repeatable terraforming projects.
But this is undoubtedly part of the efforts by the developers to "improve" the game by giving the players "meaningful choices," such as "which four extreme world types do I want to be useless to me for the rest of the game," complete with the back door of trading for the other supposedly mutually exclusive technologies to remove any semblance of sense from the technologies being mutually exclusive and reduce the choices from {(delay advanced tech to get these things) or (trade for them) or (don't bother with them until I have nothing better to spend my production on)} to {(trade for them) or (don't bother with them)}. Clearly the latter choice is far more meaningful than the former.
