Note that the “rulings not rules” is not quite that in intent as seen in the more rule light systems? It’s more supposed to be “we want to maximize player problem solving instead of looking to a procedure or ability at all times, so we reduced the number of explicit rules. DM - if a situation arises that you need to make a judgement call about how something works, give a quick ruling in an impartial manner. If you think it will be a frequent recurrence, write it down as a rule.”And I can only cry.
Because it means people think rules are stupid bad things that should be destroyed.
Sure they are. There's literally not a single difference between the two, as you've presented it. The system is meaningless, because anything-and-everything is subject to the DM's continuous rewriting. That's the whole point of rulings-not-rules. There never are rules. Ever. Period. There are only rulings, which can change, because that's explicitly the point. Having a ruling means you don't have a rule.
How is it possible for the DM to present every possible ruling in advance? The vast majority WILL be made up on the spot as the game progresses, and good luck even getting a written-down version of it!
The 2024 DMG centers “table fun” as the criteria for how you should rule, which is … interesting. OSR stuff tends to center impartiality and simplicity.
