Virtual worlds are computer-based simulated environments where users can interact with others by using an avatar or playable character. Several graphical applications are presented and described. Game design is the creation and shaping of the rules and content of a game. It includes the creation of stories, characters, goals, and challenges. It can be used for entertainment, education, and other purposes. Developing the graphics for VR worlds used in video games involves understanding how to tell a story through a mostly static environment. Different styles can be employed to represent the world: realistic, stylized or cartoon-based, abstract or artistic. There are special elements for world building in video games, movies, and literature: geology, flora, fauna, sociology, and physics. Developing worlds for video games involves a modeling package. Such a package is typically Autodesk Maya, Substance Painter and/or Photoshop for texturing, and a game engine that is either proprietary or commercial such as Unreal Engine or Unity. Immersion into this virtual world is the goal. Therefore, one needs to eliminate or reduce anything that might distract the player from suspension of disbelief.
