3e did seem to have a bit more "full conversion mods" (where classes, races, and spells were added/replaced) released; 5e has really only had AiME that I know of. Considering 5e's overwhelming popularity, I'm a little surprised we haven't seem more products that are willing to do more in-depth mechanical engagement with the system.
I mean, I know people who bought the Lord of the Rings books purely for the non-magical classes in them, and the low magic setting elements. Why would Blue Rose not want to pull in people who just want three simple classes?
