Out of curiosity, have you looked into freeform roleplaying environments? Because with that position, it seems like even the lightest RPG mechanics are an annoyance to you.Setting is most important for me, always. Whether as player or GM, I want to interact with the world as directly as possible, rather than mediated through a layer of mechanics that serve only to make me feel divorced from the world. Sure, some mechanics reflect the setting, but I have direct access to the setting anyway, so a mechanic doesn't do anything for me except intrude.
(Its perfectly legitimate to answer "I eat what's on my plate.")
