>>40124510noted, thank you!
and desu, just getting into the code & messing around with basic things like using pre-existing content to make your own focus trees, nations, leaders, news pop-ups, etc.
you shouldn't take on anything super game changing at once.
think about the endless creative possibilities, especially given the vast extent of historical content from that era not present in game, not even touching alt history possibilities, every little change here & there adds your own uniqueness to the playthrough experience
