Many game artists are called upon to develop graphical treatments for the environments and elements in which role-playing games take place. For example, in the Monster Manual early Dungeons & Dragons artists created visual representations of monsters players might encounter while adventuring. Many such depictions may influence subsequent art and the type of campaigns or adventures that developers and players create.
Art for role-playing games can be expressed in a variety of media, from pencil drawings, to pen and ink illustrations, to oil paintings or even 3D models created with a computer. Therefore, no one skill set can be pinpointed as necessary for a role-playing game artist, beyond that of some artistic ability. Necessary skills will vary from game to game and developer to developer.
