Would it be cool in these online games to have an "ancestor mode" so you could follow around and haunt the guys that defeated you? I saw something like this in Fortnite and thought it would be fun in other games, too.
And if you could have a chain on the player that defeats others too much it could be like the chain built "link by link" in A Christmas Carol.
It could add new twists to some video games, that's for sure!
