Back in August, I posted a map of the Pastside of the Washtenaw Gate, in which America discovers a portal to the cretaceous in Michigan in 1800. That map showed only the Cretaceous side of the portal.
I'm currently working on a map of the modern side of the portal, in 2023.
America focuses on expansion into the Cretaceous, and Mexico becomes the dominant NA power instead. Napoleonic France spends almost the entire 19th century trying to conquer Europe, and after a brief intermission turn fascist and try even harder in the 1930s. Soviet Russia wins a pyrrhic victory against them and out of the wreckage of Europe the Union of Socialist European States rises. Cue a cold war between Red Europe and Mega Mexico.
Still a bit unsure on how Africa and Asia are doing, though I'm toying with a communist India and a republican China.
