OK, I find that overly simplistic and not really a reaction to what I said, but again...ok.
I'm not entirely sure I understand why. It seems a clear statement: One of the greatest draws of D&D is that it provides a variety of interests and options. If you're going to cut, then for that to be actually "less is more", you need to actually prove that you are, y'know, covering
more ground despite having fewer elements. If you can't show that, then it's just "less is less". Hence, for it to achieve "more" status, without becoming just straight-up "more is more", you would need to offer replacements for the things cut--so that more is still happening. AKA, "different is more".
Far, far, far, far, far too many people love to just invoke the "less is more" maxim as though it were somehow common knowledge that fewer things could, somehow, inherently be actually more than more things. Which is ludicrous.
If you are going to claim less is more, you have to actually
show the "more" part. And if you haven't done that, why on earth would you expect anyone to buy in?
I mentioned that I think settings should be a place to introduce new stuff (rules, ideas, etc.). I also said restrictions could be minimal or non-existent. The thrust of a "narrow" setting should be to show off new ways of doing things.
Perhaps. But that entails what I argued above, no? If a setting is "narrow", it must either
actually do "more" with its narrowed, less, elements. Or it must accept being a little less "narrow" by instead being a little broader, but in areas that the cut things didn't cover--different is more.
A narrow setting is not automatically more flavorful, more impactful, more consistent, or more well-structured, simply because it is narrow. Likewise, a "broad" setting (if that is the appropriate term) is not automatically
less flavorful, impactful, consistent, nor well-structured, simply because it is broad. The work must actually be done to show the difference.
And just an FYI, when we started our last campaign I gave the players the MM and said pick any sentient creature you want and that can be your species!
Interesting. I imagine that was quite an effort on your part!
