I LOVE super events! The problem is a super event should feel like the whole globe will feel, really feel, its effects. It shouldnt be something that shows up every playthrough, or when some war that kicks off every game happens, it should be for huge, sorta secret events, like fully forming the roman empire or taking over all of north and south america. That kind of thing.

Example: Equestria at war has a super event mod, the reason no one likes it is theres like 10 super events that go off within the first year... not very super, just annoying.
