Role play is best described, in the sense of the Warriors Phenomenon, as a Forum-based collection of collaborative fiction creators. These writers work together in groups to each contribute the part of their character. The "Role" in role play comes from the taking on the role of a single character in the world. The grand majority of warriors role playing games (RPGs) are found on Forums, though a fair number are located in Chat rooms. A high quality description of the Play-by-Post style can be found at Wikipedia.
