I used to play D&D (aka Dungeons and Dragons) and from a very young age my favorite class was Wizard, elf or human with Chaotic good alignment. :)

Chaotic Good

A chaotic good character acts as his conscience directs him with little regard for what others expect. He believes in goodnes and right, but has little use for laws and regulations. He follows his own moral compass, which, although good, may not agree with that of society. Chaotic good combines good heart with free spirit.
