"Diegetics", by L. Ron Gygax
I think there's an interesting thing here. I think a large section of the playerbase likes the idea of physical capabilities of characters being a function of the ruleset and character-building, but want the mental and social aspects of the game to be handled by player skill and DM-player negotiation (The "I just want to roleplay it" request.)This was why the shift the 3E was a little jarring for me with social skills. I was always much more a fan of the Etiquette NWP which functioned as a knowledge and didn’t replace or get in the way of RP. I think this is just one of those divides in the hobby. Neither is right or wrong but for me, I much prefer allowing the players to speak as their characters and having what is said shape things like NPC reactions (obviously factors like reputation, power, CHR, can factor in). I simply have more fun playing the game this way
And yet, there's no system I can think off that builds the character as a purely physical construct and assumes the player will handle the mental/social aspects of the game. Indeed, I think there would be large outcry against such a system.
