This paper explores the characteristics of a new language for communication with game characters. This new language is called game pidgin language (GPL) (Rudra et al., 2003). A GPL is a sub-class of computer pidgin language (CPL) (Hinde and Belrose) which is a new spoken language taught to the game player and is efficient for dialogues with the computer. The GPL is extended by adding three conditions to the grammar. We add some attributes in an already established eXtensible Markup Language (XML) to encapsulate a cognitive response from the non-player-character (NPC). A complete game pidgin model is proposed in this paper.
