Some (more than a few?) gamers are profoundly uncomfortable with the greater agency and judgemental authority referees are given, especially in old-school games. Or, as my brother observed way back in 1979: "But the DM could say anything and the whole thing just breaks down and becomes unfair over time". It was a fair point, but I countered with the fact that lots people obviously were playing these games, and that unfair DMs will find themselves without players pretty quickly if they abuse their authority... He was forced to concede my first point and eventually, my second too. And the fact is, old-school gamers willingly submit to the DMs authority because it provides them with a specific gameplay experience. But the DM (GM/referee) also lives by a code of fairness (and reasonableness) that their players will hold them to!
