And yet I somehow do not see this kind of behavior in more open-ended games, so I do not believe this argument. it's not just that the players ignore session zero and you canjnot stop this kind of behavior, it's that in a more strict game some people's desire to "break it" through exploits may override respect for fellow players and poorly-designed spells like Command enable them to do exactly that. Maybe if D&D was overall more open-ended game, this would not be a problem. But not only it isn't, we're literally on forum of a website selling version of the game with 200% more specific rules. Command being so open-ended does not fit design philosophy and enables people trying to "break" the game to feel clever.
