"Trolling", was it? We all do a little trolling sometimes, haha. I did some fun stuff with doctoring maps a few times in the past, making advanced minor nations hidden on islands or deliberately adding rivers so that the most likely religion founders would auto-spread at much higher odds etc
.
I was never good enough to reliably win deity, only through TAP cheese or in comfortable diplo situations. I got > 1000 videos overall then kind of trailed off. I still intend to come back to YouTube, but almost certainly not with Civ, as my game experience last 10ish years has been Paradox games + DCSS, with quite a few other sidelines in there. Among those, DCSS is most likely, since I'm far better at that than I was at any Civ game.
Reading through the summaries, this one looks pretty brutal.
