For me a good TTRPG doesn’t need even 95% of that information because as GM it is my job to enable the players to comfortably bring themselves to the game and to control the experience. Does it matter what minute dexterity stats a character as when the game is 50% imagination? A good GM is a storyteller and therefore tells the characters how good they are rather than the other way around.

I know there will be nerdier nerds out there telling me it’s too simple but this is why I still, after 30 years still play Heroquest. Attack, Defence, HP, Mind and Treasure; everything else can be done on the fly. A good TTRPG lets the game run itself instead of relying on minute stat changes to run the experience.
