Nine years ago we decided campaign research questions were off topic. The guidance given was:

Questions asking about a general real-world topic such as history, geography or economics might more likely belong on another Stack Exchange site (e.g. History) than here. A good rule of thumb is to ask yourself …

Would an RPG expert give me a better/different/more specific answer to this question than a Historian, Geographer, etc? If yes, then feel free to ask it here.

Consider this question: Do 'light hammers', as depicted in D&D, being throwable have any historical precedent?

The question asks if the D&D 3.5e concept of throwing a light hammer corresponds to a historically accurate weapon.

Is this a campaign research question that should be closed as off-topic?
