“Ship 2 Factories froom your home city” but i only have 1 card for that.
Take a European civilization, and build a deck with 2 factories in Industrial, all European have the 2 factories to ship.
Send those 2 factories separately, and voila.
Then win the game, and the challenge is complete.
No need to win, resigning (not quitting) counts as a finished game.
Yeah, that works too, that’s how I was doing it.
