I played my first game of TFR today after giving in to the memes, having a really fun time with my first game with Die Grünen-led Germany
1EW against Medvedev-led Russia was easier than expected (many people were saying that Russia is very broken in the 1EW but I guess those claims are outdated now), capturing Moscow and capitulating Russia in less than a year, and after the war I managed to reach more than 50% federalization
I learned with trial-and-error that the EU, for this kind of playthrough, was an endgame tag when I clicked the federalize button that this only turned Germany blue and removed all cores, which is useless especially with the 2EW on the horizon, but I learned more states could be added if I supported Volt in other countries
I read somewhere that 50% SocLib could cause countries to turn blue and join a later Federal EU, but from trial and error it didn't work with Poland and the Netherlands (both of which already were 50% SocLib), so what actually causes a country to join? How many times do I have to click the button for them to be considered eligible?
