Are we allowed to call principles what we like? Like Blorb, for example?There is no principle of "Don't make the game boring for the characters." The characters' lives are always going to be interesting if you are actually playing the game. There is a principle of, "Make the game fun/interesting for the players." These are different things.
Eh, no. As posted here to show as an example, the principle actually was "Make the result interesting for the players."
If you name a principle gooniegoogoo, but write about a principle of making the game interesting for the players, the principle is not gooniegoogoo.
Nope. I criticize parts of D&D all the time. It's not a perfect game. My objection has nothing to do with criticizing D&D.
Secondarily, it's entirely possible for the game to be being played but both the players and characters to end up bored. For example, the characters are searching for a secret door. Due to other principles, the GM is not allowing for a dice roll here but is waiting for a player to make the appropriate action declaration for their character. For whatever reason, the characters aren't getting it and the players are making incorrect action declarations. Perhaps after an hour or so of this, only one player is making action declarations (I'd posit this is not uncommon as it's hard for a GM to concurrently resolve parallel declarations so falling into a conversation with one player is a very plausible play pattern). Most of the players are bored, the characters may be bored, the one player still making declarations may be frustrated (the Gates of Moria before the Watcher shows up may be the archetype of this, but I've certainly experienced it in live play). But the GM is holding true to a different principle of play - for example honouring prep and being a neutral arbiter of action declaration - that is more important than stopping things being boring for the characters. And these principles may be important for the entire group and underpin what they normally find enjoyable about the game. Perhaps having something disrupt this situation would reduce their enjoyment of the game overall - and that's completely fine. Doesn't change the fact that in this moment the players and characters are bored.
