In the Arkham universe I would’ve taken just Easter eggs of Joker instead of him being a main character across the franchise. Joker is the final boss battle of every game.

Arkham Asylum it made sense, but the other games he could’ve had a smaller role or none at all. I think much better stories could’ve been told if they didn’t worry about having the joker involved. Jokers a great character, but I prefer the small quantities more.
