Only really addressing the point in bold, but I just want to point out - as someone with Zero familiarity with the term, from the term "Mother May I" I could instantly tell:
- It dealt with needing 'permission' to do things.
- Within the context of a D&D forum, it almost certainly referred to issues with the DM's handling of the game (as they wouldn't need permission from the players).
- It is being seen in a negative light.
Just saying, that is a LOT of information conveyed in a term, because it's largely self-descriptive. Now, you don't need the information, as you're already familiar with it, so I can see how it would not be useful to you. However, as someone coming in fresh to the discussion, if you were instead to use the term FKR or "Free Kriegsspiel Revolution", unless I happened to know German (which I do but most don't), the term would convey nothing of use to me.
Now, I can see how you would have concerns over the negative connotation coloring the conversation, and I can understand the challenges associated with folks conflating the specific complaints and negative comments associated with "MMI" with an entire playstyle. But as an outsider, I find it a much more useful term than FKR, for the same reasons that "Centigrade" is an infinitely superior name to the temperature system than "Celsius" is.
So let's unpack this a little.
Let's start with your third point.
"It is being seen in a negative light."
That's what I have repeatedly saying. Now, if you listen to some of the people on this thread (that I do not wish to summon), they will claim that this is just a neutral term. "Just calling it like it is."
That is wrong. You acknowledge that. I'll quote
@payn who correctly stated the issue on the first page-
Like many of these derogatory remarks, they do contain legit concepts. Its just a very clear flag planting of where the person's line in the sand is. My advice is to either ignore the insult and focus on the example and discussion, or just ignore the comment if it seems like a position stand in place of any genuine interest of discussion.
That's what the issue is. I brought up FKR because it's a relatively "pure" example - but the actual OP (and primary usage) of MMI has nothing to do with FKR, which is far too niche. Instead, it's about "rulings not rules" in 5e or OSR play.*
Look, if I describe games that have a lot of rules as "Mindless Button Pushing," then you could say that (to quote you)-
- It dealt with not wanting 'permission' to do things.
- Within the context of a D&D forum, it almost certainly referred to issues with the players being able to rely on the rules to get pre-determined outcomes.
- It is being seen in a negative light.
Right? Simple. But the third point is the most important. If someone uses that term, I know that they are using a derogatory remark, and are planting a very clear flag as to what their preferred style of play is. It's probably not worth engaging with them substantively.
Same with MMI. People have preferences- and there are advantages and disadvantages to rulings and rules, which has been a push-pull that predates 5e, predates D&D, and goes back to the original Kriegsspiel / Free Kriegsspiel split. There isn't a "right" answer- just relative preferences for the things that are provided by it.
*Again, OSR play became popular during
3e as a reaction to the abundance of
rules.
