Character Behavior involves several complex levels and expressions. The most important behavior standard is being in Good Standing with any Guiding Behavior. Many advantages gained from institutions, faiths, and other Bonded Codes rely on this. Character behavior is a centerpiece of the role-playing experience on all levels.
"But, it’s what my character would do!" - These types of character aspects are not an excuse to be disruptive to the point that it constantly endangers the safety of the group or the story continuity. Find creative ways to work through situations and do not manifest them to extreme levels of Behavior for your own amusement and to the detriment of the group.
What are the limits? Obviously certain behaviors can cause conflict and chaos. While some of this can be fun, it is a balancing act. Be considerate. You can enhance the fun for the whole group, but its easy to place too much emphasis on an aspect and be perceived as having Main Character complex or just being inconsiderate of everyone else.
This presents a good opportunity for adding Character Story elements to the Character.
