Link to doomed hero and painlord. Adding my own thoughts from a player's perspective.
I like to play when other players push the action.
It is hard for me to know if I am playing well when others do not push, and it gives more feedback.
I am eager to see the results of things that my character does, and seeing others push brings results faster and also creates things that are unexpected.
I do not want to be the only one controlling the action, or I would just write my own stories.
