The Metaverse, with all its possibilities, will reshape society, change markets and affect our environment. It will also, just like the Internet, be subject to global discussions and worldwide legal regulation. To pro-mote a responsible and ethical Metaverse, we have created these 42 statements. We want to participate in an open dialogue to help to place the Metaverse in the context of society as a whole. This first version of our Playbook lists some important aspects for the upcoming discussions, meant as a first step in shaping a responsible approach to the Metaverse, to be complemented by practical guidance and advice in the near future.
