Pushing the date back forced introduction of proper levies and mechanics to transition away from them. Mechanics that they introduced and that seem to work well, so good. Ig we just have more of a good thing per thing, that is, more playtime per playthrough.
I said once I will say again, the only thing missing from game mechanics, to be also capable of simulating 1836 to 1936 dates is pops having political views. Unlike EU4, I put a lot of faith into extended timeline mods, because now there are mechanics to accommodate and properly show specialties of other eras.
There is said to be a factory building in EU5.
