Because there are 2 copies of UGameInstance created: CDO and Instance.
Instance calls Init, but there is no Exit, i would like to place cleanup code there for my game.
Now i am using UObject::FinishDestroy(), which is called twise: for CDO and Instance, not big problem, but still.
PS: i know, i could override UGameEngine and UEditorEngine classes, there are PreExit and Exit. But as far as i understand, i should override only UGameInstance for that purpose.
Also i think, i dont like to override both Init and InitPIE, i would like to have smth like generic InitGame.
Not big problem, its just a suggestion.
