I think it does. Not in the effect that age is experience. I've been RPing here and with folks before here on TGC as Captain Colbs, RC 212, and host of other characters. Some of these folks have been here for a long time. When I started before the switch to this board I think I was about 15?
Now I'm 24, fast approaching 25.
I've noticed my writing and how I handle folks has changed with age. One notable difference right off the top is I don't take everything as personally as when I was younger, and I'm not as much of an ass to folks any-more either. When I was younger I was much less mature about the way I handled things. My characters were cheesy because I hadn't had that age and experience.
Now with age you learn more about people. About purpose, what drives folks in real life, what things are actually like. Your education level is generally higher the older you get and therefore you have a deeper well of knowledge, wisdom and experiences to draw from and infuse into your character. Many of my characters have been reflections of what’s going on within my self.
When things are going great I tend to write lightside oriented folks. When things are rather Chaotic In my life I tend to write more darksided characters. With age I've come to understand what drives each a little better.
When I was fifteen I was more into writing the whole, "I go to a planet, mess everyone’s day up and generally cause hell."
Then I graduated to the "Hell raiser, but fun plot twist guy."
Now I still like to stir the pot, but as I've changed over the years so has my attitude towards characters, and the world. It's reflected in the type of writing I do. I'm more concerned with telling an amazing tale and really driving a characters development rather than being super Clone Trooper Warlord X. I generally try to stay away fro screwing with people IC just for the sake of it. Except with Jack, but that wasn't personal. That was just how I imagined he'd feel IC and the actions he'd take IC.
