So I thought I would try an ironman game playing as Brandenburg. Made a solid start and saved the game after about 30 years of game time. Just went to resume it and it was so unclear to me how to do so that I ended up overwriting the save file and have now lost the game I was playing. I'm amazed that such a well-designed game does not make it more straightforward to resume a saved ironman game. Easy when you know how, no doubt, but not clear at all to a relative newbie like me. Boy, am I feeling pissed off right now!
