Codes of Honor

As mentioned in the Character Generation Forum, Codes of Honor are just optional guides. They are offered to help paint a picture about the behavior of some of the members of different communities within the setting. They may be followed by some NPCs. Some of them are generally associated with certain regions or with certain human sub-races, but they are not universal. They are not required to be adopted by PCs, and even if they are adopted, they can be adhered to or broken as decided by the player.

Reference Note: All of these codes originate from Mongoose Publishing's Conan RPG. Great ideas that I think lead to many interesting role-playing situations and more complicated decision points within a game.
