First, read this paper — Beyond the Rules of the Game: Why Are Rooie Rules Nice? The main take away is that the children there are using ostensible rules that aren’t about what they claim to be about. They’re not about discrete, clear actions in the game, they’re about an ill-defined way of interacting “nicely”. And that’s more important than the literal rules.
The article is about children of decidedly modest years. We adults are much more sophisticated. Does that mean we’re also more confused by our own smoke and mirrors?
Next, read Shroeder on Tuovinen on D&D play as a system of rulings with precedent. Tuovinen’s thread wouldn’t load for me (Forge archive structure has changed?) but Schroeder summarise it thus:
One fascinating document is the discussion of Eero Tuovinen’s D&D campaign. There, he treats D&D rules as oral tradition. If people remember a rule, it is applied. If a new rule is proposed on the spot, it is applied and if it remembered the next time such a situation comes up, it is applied again. The rules are what people can remember. Slowly, rules fade out and new ones fade in. It’s a living, mutual understanding of how the game will be played.
Third, read this Twitter thread by John Harper on how Blades in the Dark is no more complex than World of Dungeons. Key quote:
… They feel similar to me in play, but one text leaves it to the players to figure out all the steps and methods, and the other text spells everything out. …
I’m pretty sure Harper is wrong here. Most groups, if they took World of Dungeons as a text, wouldn’t explicitly figure out steps and methods. They’d figure out something, for sure, but it is not “steps and methods”, not in the sense that Blades’ rules consist of that.
Finally, go and write your own blog post explaining the important connection between the three articles above that I have failed to describe or indeed to know.
(Bonus activity, for the very eager and alive — (re-) read Patrick Stuart on how BX/Moldvay D&D is the common language that makes the OSR space work, and try to work out how it can be true, given the above)
