you can set it in future or 90s, slightly or fully change flags, set the conflict in slavic region countries, add custom lore, add your own depressing buildings here (to add khrushevkas gray feeling) like rainworld buildings
you can compare block of flats (krushevkas) to Humant colony lol which makes street fights more suppressing
For developer
A little bit of history: The POST SOVIET countries has a feeling of ancient civillization which on its way to progress died/collapsed and got erased by some unexpected events and now all these buildings, people, technology is just remnants of something greater, thats what made 90s depressing and also started a age of tons of conflicts and it still continues on which getting support by the worst human sins
Gl with game, i hope you wont attract there toxic players, cause all this stuff is such rabbit hole
