I really like Kaiserreich because it strikes a good balance between the more ridiculous elements of its premise, like Mittelafrika and German East Asia, and showing realistic consequences of that map--namely that DOA is a house of cards with the Viet Minh & friends running rampage left and right, China is a frozen conflict and the LOEP is outright FATED to implode due to being run by the worst pieces of shit in the entirety of China (yes, even compared to Dai Li and the drug smuggler and the cult leader, these guys are shitstains), and Mittelafrika WILL blow up if the Nazi idiot in charge of it gets his way. Hell, even in the pre-rework build, EVERY German puppet in Eastern Europe has a rebellion path and is likely to take it (Lithuanian ultranats, left or right Poland, UBD civil war, Finland's left and far-right paths, Ukraine left and right (IIRC Ukraine is GUARANTEED to quit either way?), Belarus has several paths for rebellion too).
Red Flood could do with more realism, but I genuinely think it's better as the "crazy town" it is, because I really want to play Nuclear Einstein's Socialist Utopian Pan-Levantine Federation. It doesn't have to make sense because the fun is playing stereotypes and tropes and weird ideas up to the absolute maximum and not caring about realism.
