This guy (and his group) is from one of Ron Edwards' essays.
I assume he (and his group) exists. I never met him (in person anyway). Have you?
I have met dozens, perhaps over a hundred, very experienced role-players with this profile: a limited repertoire of games behind him and extremely defensive and turtle-like play tactics. Ask for a character background, and he resists, or if he gives you one, he never makes use of it or responds to cues about it. Ask for actions - he hunkers down and does nothing unless there's a totally unambiguous lead to follow or a foe to fight. His universal responses include "My guy doesn't want to," and, "I say nothing."
I have not, in over twenty years of role-playing, ever seen such a person have a good time role-playing. I have seen a lot of groups founder due to the presence of one such participant. Yet they really want to play. They prepare characters or settings, organize groups, and are bitterly disappointed with each fizzled attempt. They spend a lot of money on RPGs with lots of supplements and full-page ads in gaming magazines.
