“Fair and Balanced” is not just a Fox News blurb, but a constantly cited principle for RPG game design. But what is balance? An arbitrary viewpoint? Neutral game mechanics? “Fairness”? Often it comes down to personal opinions and long accepted norms established long ago in D&D.
RMU development is a perfect case study in the tension between rethinking a ruleset and an unquestioning loyalty to RPG tropes. The most basic assumptions are often the most discussed: Magic Users can’t wear armor; magic is broken down into 2 or 3 realms; the balanced party (Fighter, Thief, MU, Cleric); Class tropes and the definition of a particular class, etc.
