How do you deal with anachronisms in your #ttrpg games?
Say a character would like to invent a bicycle in a medieval setting. Do you let him?
@kingu Do wheels exist to the character's knowledge? Clockwork? Could they create the chain? What kind of understanding of how balance works does the character have?
If all the pieces exist in-world, I wouldn't be inclined to stop someone, especially if they've specifically made an inventor character.
Also, what counts as an "anachronism" can be fuzzy in actual practice. One society's novelty toy can be another's practical breakthrough.
