Previously, I had assumed that this would be the basic structure of 5E:
- Basic: similar to Moldvay, simple traditional classes
- Standard: more classes, feats, and other build options such as multi-classing
- Advanced: detailed tactical rules, miniatures, domain rules, etc
However, it seems like in addition to detailed rules for adding depth to particular parts of the game, "advanced" will also cover a number of what Mearls calls "dials." That is, guidelines about how to adjust things like XP rewards and lethality. These elements would replace elements of the core game rather than adding to it. Anyone who has been following my blog recently knows that these are the things that I am probably most interested in adjusting when tinkering with rules.
This seems like an excellent way to structure the game, and I really look forward to seeing the final presentation.
