D&D is the McDonalds of RPGs...Just look at McDonald's. I mean, Ray Croc McDonalds. Benefiting not from healthiness or good food but price and marketting.

McDonalds is: Sufficiently tasty to be edible, sufficiently bland to appeal to a wide variety of palates, sufficiently varied in menu to allow for wide range, sufficiently cheap that it's OK that it's just good enough to remain edible.
D&D is: a genre engine, not a setting engine. Just good enough to be playable for most of the gaming populace, in recent (3e onward) insufficiently offensive to drive off most not offended by its complexity, sufficiently complex to have meaningful build choices, sufficiently simple enough to allow newbs to grasp the basics in a session or two.
Both have become the cornerstone of the industries they are in.
