An interesting idea for a new reward can be "What if your favorite game ended differently?"

Imagine changing the final cutscene, rewriting that last choice, or simply changing how things ended.

For this reward idea, creators can reimagine iconic endings in their own way through edited cutscenes or narrated ending with visuals from yhe game or even text with screenshots

Doesn’t have to be an alternate story, just a different ending. Just change the feels of the finale!
