Background. To facilitate game sessions for purposes beyond mere entertainment a facilitator needs to act like an ‘Unseen Helmsman’: steering their ship clear from rocks and storms without the players in the ship realizing. Previous work laid down a competency model for game facilitation. It reviewed several competency models for facilitators of generic (non-game) group sessions. Since no such model comprehensively provided guidelines to facilitate game sessions in particular, a new competency model was proposed using a bottom-up approach with the participation of game facilitation experts. The question remains what lessons may be drawn from this model.

Methods. This contribution elaborates on the competency model for game facilitation and draws lessons from it. Thus it aims to empower both novice and experienced game facilitators to become an Unseen Helmsman. Also, it presents learnings for people who are experienced in facilitating groups in general, but who are new to facilitating game sessions.

Conclusions. First, lessons for novice game facilitators include familiarising themselves with the core notions of the competency model: the characteristics of a complex systems game (session), and the attitudes, knowledge, and skills for successful game facilitation. Second, experienced game facilitators may learn from existing competency models for generic (non-game) group facilitation. Third, facilitators of generic (non-game) group sessions are encouraged to study the characteristics of game sessions in addition to the specific competencies contained in the competency model for game facilitators.

The facilitation of game sessions is an endeavor that requires specific competencies. A game facilitator needs to be an ‘unseen helmsman’ steering his/her ship of game players clear from rocks and storms without the players realizing. However, the competencies required for game facilitation are somewhat shrouded in mystery. In the past, several competency models have been developed for facilitators of generic group sessions. However, among facilitators of simulation game it is assumed that facilitating gaming sessions requires additional competencies. Currently, there exists no model that comprehensively outlines the competencies needed to facilitate a simulation game in particular. In our study we determined what makes facilitating a simulation game stand out with respect to generic group facilitation. Then we performed both a top-down literature review and a bottom-up, participatory study to propose a competency model for game facilitation. In the former we investigated several existing competency models for generic group facilitation. In the latter, we guided a group of game facilitation experts through a four-step process to identify competencies. First we asked the group to identify skills, knowledge, and attitudes that are needed to facilitate a simulation game. Second, the results were analyzed by another group of experts and submitted to, third, a hierarchical cluster analysis and, fourth, a ‘labelling game’ to identify competencies. We compared the outcomes of the top-down and bottom-up studies to draw conclusions. We found that although some competencies from the literature on generic group facilitation are valuable for game facilitation as well, others are not applicable in a game facilitation
