In my current game, I got crushed.
I dont own any military.
My capital has 7 population, and 8-9 tiles non destroyed.
My second city is near to it and has one faactory, 50 non sick population.
It is clear that I lost. But I am an honorable man, I dont abandon my OWN people!!
So I keep playing. I tried to build a second factory. Actually even the first factory in my second city is built under heavy gunfire. They did not destroy it. By the way by "them" I am meaning Burlusts, Boarines and Thoraxians, so yeah I really lost the game.
Each turn, if I have some money, (my income is as low as 3000 a turn btw as you can expect) I try to build some new houses to my second city, which is a little less destroyed, and sometimes I try to build some military, but they immediately destroy it. So it is like a vicious cycle, I know that I am lost, 3/4 of my population is sick always, and my income is getting lower and lower.
Basically, I want to lose, but it has been more than 45 minutes to with light of end of the tunnel is in sight. I was gonna say "2 hours" because it was that boring , then checked Steam gameplay time.
What I can suggest is, there should be some fatality in war, while indecisiveness make it longer and grindy, in the cases clear like this, the player should not be forced into abandoning the game.
I think Losing conditions are not being worked as hard as victory conditions, which I know also are not complete.
