I think we may be talking past each other. I was just reacting to the idea, that might not have been your intent but that I felt when reading the thread, that curated list implied being a bad designer stuck with ME clone level of GM'ing, a somewhat negative view of that. Sure, if your goal is to get more customers, you need to make change. But outside of the fringe case of a hired GM, the GM is not here for money, he's here for fun, like any other player, and doesn't need to change anything. They (both the GM and the players) just need to find group with matching expectations.
