Even I admit to having shared some traits between every character I've ever done before, or perhaps imagery of what I like one to be. But they almost always had some similar trait regardless of how I thought of them. While I have little life experience for many of the traits I do think of otherwise, some still linger in there. Heck, technically my first one was an "orphan" as well but for other reasons. It had a small reason that swayed that decision that I got from RL, definitely.
Love the food for thought this thread gives though.
The first chat I made back when we founded S/D (later renamed BHG|). I even named the character with my own name. The female character I made when founding GMG| was based on the darker and sinister rumors of GMG but I never expected that char to develop into my main that I used for quite a long time. Aside from my first steps using an already present written foundation the char truly developed anD refined through interaction and diplomacy with other players.
Some excellent points. Of course many characters are intentionally very different, but when it's a channeling of experience, the characters can be much more interesting.
And not necessarily traumatic instances either. Perhaps a channeling of fascination, or excitement. Anything really.
Allowing for genuine emotion, and going off of experience can always make for interesting stories, and believable characters.
