Game designers include training levels in video games to prepare players so that they can enjoy the game. The training levels of virtual reality (VR) games are typically assumed to be within the virtual world of the game. New players must learn about a new game in such an unfamiliar virtual world. A tutorial in the real world offers a potential way to enable players to learn about a new game and to practice the skills in a familiar world. To explore any effects of a real-world tutorial in VR games, an experiment was conducted, the results of which show that a real-world tutorial is effective in helping new players feel confident about and familiar with a VR game before playing it. However, it is not as effective as virtual-world tutorial in increasing game performance.
