A Victoria II mod, based on Vanilla*, tries to recreate the game in a 1700-1821 timeline. (We're also looking for new devs, more info on our discord)
The Classical music submod is a collection of 10+ songs from the Age of Reason, from famous military marches to the works of Vivaldi and such it functions as a seprate mod, so simply select it along with whatever other mod u want to use this with, and enjoy! (This submod should not change game checksum)
