A new eras gamemode

I was thinking about a new game mode idea that in my opinion would be very fun! What if there was a mode where you can control what happens in the whole football world and you could also choose what eras? Basically a fully controllable simulation mode where you can choose what teams you control and what year you start in. You could be able to control transfers or even manager sacking and movements. I don’t know if I’m the only one that finds this interesting but I hope I’m not alone on this. Thanks for reading
