User-Centered CBR Technique for Characters Design in MMORPGs

This study conducts a user-oriented approach to create concepts for new game character design. We use a vector, involving a number of character attributes, to represent a character. The characters’ attributes are defined by how game-players perceive and interact with the character, by following the initiatives of user-centered design. A character database is established by collecting these characters and their attributes. The database provides default characters as benchmark to create new character concepts. We use case-based reasoning technique to retrieve “sufficiently relevant” characters from the database to be the benchmark characters. The features of the benchmark characters are manually screened to identify creative and preferable concepts for generating candidate characters. A preliminary prototype system based on this approach has been established.
