It should work for all Hegemonies, those added by other mods as well; although I'm planning on adding irrigation systems and those will be tied to regions.
Sorry for late response, Steam doesn't notify me of those posts, so in future its better to also write in the comments.

Never mind. Thanks for the info.
What about a project to build a grand building? So that it could be built even without a legend?
Or a grand holiday project that would raise taxes, promote happiness, and promote development for years to come?

I would prefere to keep the legends rewards unique to them; grand holiday is interesting though, maybe like a Roman Triumph or some sort of festival, although I feel it is more of a thing for an activity, when I think about it

Yes, but this will give a buff to almost the entire state, and not just a small bonus to the county like a tournament
