Moreau Vazh wrote an excellent post on their blog Taskerland, entitled “System Matters, Explicit Mechanics Less So”. Framing the debate on rules density historically, the post points out that gaming groups end up behaving in patterns similarly seen in many groups of people who have come together to do something creative. Of course, given that the norms of roleplaying are a great deal younger than, say, the social conventions of playing music in a group (an activity which is highly delineated and has many, many titles associated with said groups), there’s still a lot of push and pull in terms of figuring out how everyone actually wants to roleplay. Many of the norms we do have were developed either from prior art (often wargames) or came up simply because they were written into D&D back in 1974 (or perhaps a few years later, depending on the actual rule). Either way, these norms are still evolving, and as Vazh correctly points out, the hobby spends way more time agonizing over mechanics than attempting to understand the social dynamics which lead to game preferences and styles of play. And this leads to the core thesis of the Taskerland post, that ‘system’ is so wrapped up in the social norms and conflict resolution approaches of a group that the way a group plays games often transcends mechanics.
