I don't know if the title is explicit enough, i'll try to explain...
Before i even knew what role-playing in Skyrim was, i already did stuff that made sense to me despite the game not "recognizing" my actions. Basically, i'm asking which role-playing rules came naturally to you.
Mine:
Never wear helmets in cities. That always felt stupid to me, having my face covered/half-covered when visiting a city or entering someone's house. Same with heavy armor, i don't use heavy armor in cities, i change to fine clothes or something more civilized. Light armor depends.
Don't walk around with weapons drawn outside dungeons.
Don't run like a fool in towns, fast paced walk? Fine. Running? Rarely.
Hope you understood my question, now share yours
