Abstract <p>Unique aspects of game design documentation development for massively multiplayer online role-playing games in virtual reality (VR) are considered. The relevance of and challenges in designing such games are discussed, existing approaches to creation and adaptation of documentation for VR are described, and such key issues in VR as network interaction, immersion, and the interaction of players and nonplayer characters controlled by artificial intelligence are defined. A methodological approach to the construction of a game design document for games of this genre is proposed, drawing on the example of a technical specification of several games having a focus on structuring and standardizing the document. Future directions are discussed, including formal descriptions of game logic for scene portability, perspectives on auto-automated VR porting, and tools for auto-generation. Finally, the importance of standardizing technical specifications is emphasized and directions for further research are suggested.</p>
