if I want to find a negative point, then I would say that I am sorry that I can not sell even produced weapons and armor, but these remain to eternity in the list. which was with the original different because I was able to build plasma weapons without end and sell them. but so be it, the game would become a little more demanding, which again is a good thing then.
definitely a must for all strategy fans, for fans of the X-COM series anyway.
