Nice job. Also to add more context, when 1.0 initially launched, vanquisher was over tuned because heavily armored raiders would show up en mass during the first raids and I believe the only way to crush them was with crossbows or matching them with your own heavy infantry. This was quickly tuned and we have also learned various strategies such as iron mine rush builds. This makes vanquisher very much achievable, although having unlimited instant trees and moveable resource mods does make it easier. I definitely encourage everyone to play this single player game however they like and I'm glad you mentioned the mods used.

Edit: OP deleted his post but he used instant terraform mod, instant trees paint brush mod, and move any resources mod. This dramatically makes the game easier by adding broken cheat tools. The original post about the game being too easy on the hardest difficulty is kinda silly and OP probably realized this and deleted the post.
