you mentioned having a human au, so how does it generally work? or like a specific character from it you wanna talk about :)
the human au is pretty much completely disconnected from the countryhumans.. the only similarity really is the initials of the human's full names and the countries' usernames.
all countries in this au live (almost) normal lives in new york city. the primary reason i chose the location was due to it's history of being an ethnic melting pot and therefore being a reasonable location where so many different people with different backgrounds could meet up and interact with eachother on a semi-daily basis. i also know a lot the city and it's history which makes the whole thing easier for me to write about.
countries aren't assigned to boroughs like the are to continental cities in the ch world and are instead placed in locations with large populations of the countries' primary ethnicity; i.e poland lives in greenpoint (i almost wrote greenport sorry. she does not live in long island), ussr and his 2 children live in brighton beach, and so on and so forth.
obviously major events like whole wars can't happen (aside from like, street wars and whatever but i don't get into those for my own sake) so major events such as those get scaled down heavily to city-wide crime sprees and whatever. i still try to make events semi-parallel to the ch versions so LOL. some major things do change though. including the fact that italy is not in the picture at all due to being in witness protection lmfao
character's personalities are also different due to the differences in culture between ch and people. like, poland is much kinder in the au due to the fact that she actually had to get a diagnosis for gender dysphoria and due to that kinda also had to work through her personal problems.
the years of the au is probably between the late 90s to now? im not sure the details. however the time period in history in which the au is currently in is.. I'd say around mid-70s or something like that. instead of being actively hostile eg and wg straight up don't know eachother. they don't live near eachother (completely different boroughs actually. wg lives on the upper east side and eg lives in. i already said it but brighton beach. aka the far side of brooklyn) and their schools, while much closer, aren't to the point where. Well they'd actually see eachother a lot. also they'd continue living separate lives instead of reunification.
countries with different cctlds that are still children have their first and middle name be the cctld instead of first and last. also some don't use their cctlds at all.. i use the "eg" acronym instead of "dd". eg's name is elizabeth lol
hope this explains some stuff. feel free to ask questions!
edit: also certain things dont happen or just. are edited severely. some countries while annexed move out of nyc and come back after a few years to represent being un-annexed
