Full immersion is the unreachable desire of many larpers. A reminder of our first larp. A demanding path that rewards with deeply moving experiences. But this approach is not free of danger, one of the most relevant being the possibility to prioritize the characters desires over the larp ones.
The steering technique allows to modify non-diegetically the direction and motivations of a character. This while useful, requires an extra effort for the participant and creates an immersion gap. Therefore a diegetic steering approach would be more desirable.
