Man, I have so many thoughts about this. I was a professional actor for about 10 years, so, you know, I have a whole other gear I can throw it into at the table. For awhile I enjoyed putting on a real show and people seemed to dig it. But then I started to get more interested in what everybody else wanted out of the session, I guess on the theory that I could usually get my jollies when I needed to. Also, I started challenging myself by playing other sorts of “parts” at the table. I can do you a Wolverine-style smartass in my sleep, but what else can I make work for me?
So I think I focus on being a Good player now, and I’ll push toward Star if the story comes toward my character organically, of if, like you said, the boredom starts to happen. (At least that’s what I think I’m doing. Maybe I’ll pay attention to this at BigBadCon in a couple of weeks.)
