A Case Study for the Approach of Converting a Mobile RPG to a Multiplayer VR Game

In recent years, multiplayer VR contents have been developed and are in service in which a number of users cooperate or confront each other in the same physical space. This type of content should be provided in a first-person view. In addition, the positions of the users' HMDs in the real space where the actual users are playing must be reflected in the virtual space in real-time. In this paper, we propose a solution to consider when creating these VR contents. We also explain a case where a mobile RPG in service is converted directly into a multiplayer VR game.
