[RPG] Is it metagaming if I want to build a bomb

dnd-5emetagamingroleplaying

In a hypothetical situation, I want to destroy a castle's walls. To do so I came up with the idea to build a bomb a la Saruman in LOTR. Perhaps my character would have to dig around for records on bomb-making, search for the ingredients, and finally craft this device, as par the course for an RPG. However in retrospect my character might not even know such a thing exists in the first place. Certainly Theoden did not realize that his castle could be overcome by such a device, and made no precautions against it in LOTR. Thus, would undertaking this plan be considered metagaming because it came from knowledge that I knew, outside the game?

In this situation: if you have to ask, it's almost certainly meta-gaming.

This sounds flippant, but it is not. This could also be construed to apply to any meta-gaming question, but I do not intend it that way, I intend it for the narrow class of, "Is it meta-gaming to build X?" and closely related questions.

Meta-gaming, very tersely defined, is the inappropriate application of player knowledge to guide character actions.

In this case, the player knowledge is somewhere on the spectrum of, "There are chemicals that can be made to explode," and "the chemical formula of TNT is and can be made by the following process; see footnotes for procedures to avoid blowing up self." In other words, you the player know bombs exist. You might know a little or a lot about how to build them.

The desired character action is, "The character builds a functional bomb of some sort, by some process."

The thing that makes this sound meta-gaming is that there is no obvious and appropriate link between the character knowledge and the character action only between the player knowledge and the character action.

Conceivably there could be. We don't know much about this game setting. It could be a post-apocalyptic earth with legends of explosives. It could be the Guardians of the Flame universe, which was straight-up fantasy where conventional explosives worked. It could be some homebrew fantasy where dwarven miners are rumored to use such things. On the other hand, it could be homebrew fantasy where explosives just don't work by divine/GM fiat, period.

What causes me to think that this is meta-gaming, and what causes me to formulate the answer as "If you have to ask, it's probably meta-gaming," is that by the phrasing of your question you don't know, either. As you say:

However in retrospect my character might not even know such a thing exists in the first place.

If you're not sure where it is your character is getting an idea, it's probably coming from you the player, and not the character's interaction with the game world. That makes it meta-gaming in my book.


As an addendum, some level of meta-gaming is almost unavoidable. We as players have a rich and detailed first-hand knowledge of exactly one world (the real world) and probably shaky knowledges of other fictional worlds.

It's almost unavoidable to ask questions like, "Hey, does this world have gunpowder?" or "Does this world have xorns I could capture to eat the castle walls?" purely in order to efficiently sharpen our knowledge the game world we're playing in. But you can avoid going very far down those roads by asking your GM and then abiding by his or her answer.
