With your collection keep the Simpsons. You already have a game with GOTG basic shot path (Met) and a game with GOTG basic rules (KISS) so you aren't really gaining anything. If you had nothing but stop and go games I would suggest the change as GOTG has some good flow "if" you are hitting the shots. But since you already have several games that basically cover the play and rules of GOTG I'd keep that Simpsons to keep the diversity in your collection.
