This theme is not a theme, it's a constraint.
The theme should be interpreted somehow by the author of the game, but shouldn't be a special rule. The rules didn't say: the game must follow the rule in the theme reveal video. One theme could possibly have multiple interpretations, and the theme should be a hard rule. It should be something to build the game about. And the theme rating is how good does the game fit the theme. In this jam, the theme rating will be random. Should I give everyone 5 stars because it's based on a starter. That would defeat the entire purpose of the theme rating. I'd go with giving everyone 2 stars, except if the game fits the theme (fits - not fulfills).
