Can I statlessly role-play myself as others see me? For instance, I have a reputation for being in more than one place at a time (as per my secret passages in every place I frequent...), and I figure that by the time a convention is going on, I can be in and out of corners and hallways at all times. Probably saying things in the background that make absolutely no sense, or muttering about food sleep and video games, and why I love buffalo chicken strips. That's the real me, no need for statistics or gear .
However, I would think things like these apply: (weapon Focus, proficiency, and specialization in video games, with a non-proficiency penalty to sports titles, racing games, and platformers, skills being Craft: Post (+10 competency bonus for my sig), Profession: Pulsing Brain, Perform: Way too much, and finally Video Game (+10 competency bonus for addiction, -5 to all non-dork related activities)
