I’ve only purchased a few. I’m not totally sold on them. I bought (and sold) Star Wars just like I did the game.
I have the Stranger Things topper (the only one in my collection now).
Other than that just a few. A good friend gave me the Haunted House / AMH Laseriffic topper for my AMH. It was a good fit for the game. I included it with the game when I sold it.
While I don’t care for most of them, some really stand out. KISS and Black Knight come to mind.
