So I have to say after 3k+ hours in Civ 5, I've gotten to basically be an ironman player in just about every 4x game I play. I never save other than maybe to backup every now and then in case of game crash, and I just accept whatever 'turn' happens.
But in DW-U, I have one condition which I do kinda bronze man as a rule, and that's if my random game start has a home system with zero gas giants.
I completed a game recently where my home system had zero gas giants, and it was a massive pain. My huge mega shipyard would crank out ships but there'd be no fuel to fill them up, so with almost empty tanks they had to limp to closest system to refuel before even being ready to assign for something.
Yes, I did the obvious workarounds. Build resupply ships as fast as possible, go park to start building up huge cargo of fuel and then eventually park them in my home system to server as military ship fuel depot as civilian ships don't use resupply ships, but it was still a pain - especially as it took awhile to eventually get energy to fuel conversion tech.
Not sure why the private sector didn't just move and stockpile massive amount of H/Ca fuel at my home system (overall stock I had huge amount, just not at my home system).
But anyway, that is so far my one condition for auto restart when I open a new game and see my home system doesn't even have a single gas giant in it.
