There seem to be smattering of questions about Dungeon World of late, which is apparently a system with very specific rules as to what a GM can and cannot do. However, the wiki entry doesn't include a single mention as to this quirk of the system, instead only including a marketing blurb from a 2012-era kickstarter.
The Dungeon-World.com System page would be a better start if a quote is necessary, as it at least includes an implication that this RPG has different assumptions than those you could pick up at a chain bookstore. And of course, if there were a good "this is how DW is different from other games" page, it would probably suffice for a replacement from the marketing blurb. But right now, just from the text listed, it's hard to tell at a glance that Dungeon World isn't just D&D with two six-siders instead of a d20.
