Oh wait nevermind ignore me, I misremembered which modifier was which

@Orangechrisy I just put <FreeBuilding></FreeBuilding> on the wonder so every city gets the Great Work slot

Oh yeah how do the great work slots per city in the empire things work? I thought great work slot stuff can't be stacked so having multiple of a dummy that gives slots wouldn't give them, but I may be wrong, it might just be a visual thing and they can still get works put in their slots even if you can't see. At least the Dynamic Culture Overview stuff I don't believe would show them separately (in my Dutch Civ Pack I made four separate identical buildings so that the Culture Overview would show them and allow you to move the great works around).

Yeah, I've done it for a bunch of my civs like Lesbos if you want an example. Just gotta put the two files somewhere in the mod, set their VFS import to true, and it should be good to go (though always good to test to make sure ofc)

@Orangachrisy Wait it's possible to do that? I'll be sure to keep that in mind for the future.

You can include the Culture Overview files directly into your mod (I normally put the two files, the CultureOverview.lua and CultureOverview.xml into their own folder in a lua folder but doesn't matter much) with VFS import being true, and that should let the slots show up for you without needing to have any other mods loaded.
