Yeah I think atmospheres would be good addition. Like a derby game you hear the passion from the fans and supporters
The chants they sing etc problem would be licensing them as they don’t have the rights for the EPL YET. (I believe it’s coming on year tho)
tbh I don’t play with sounds on anymore as a huge lover of fm and for playing the game back when it was championship manager I would like this in game. And some of the opening posters features as well.
