The individual steps of the experiment are depicted in the graphic. The player pairs played the exertion or the non-exertion version of the game for about half an hour. The rest of the experience was identical for all players.They were told that their performance was not being measured, but that the goal of the experiment was to hear about their thoughts on the system and to see how much they enjoyed it. After the participants played the exertion or non-exertion game, they were asked to fill out a questionnaire. Subsequently, both participants were brought into the same room where they were interviewed together.
