Looking how to end this scenario, Slow and Steady.
I have met all requirements by 1940.
EXCEPT, eliminating all opponent companies. I merged with them all. None on the board. Game does not end. Then with the money they have, they just start new companies. And start the process all over again.
Is it too late? Did I have to do some financial playing around at the beginning of the game, to ensure the opponents never got enough money to start additional companies? Is that even possible?
Any way to win now?
