— a player, Steam review · 8 hrs played“Even after all these years, I still find MOO-II one of the BEST video games of all time... even with the outdated graphics, it was soooo well programmed that it is playable for hours on end, without bugs, and gives you a good balanced game. If only I could say the same things…”
