Noname manuscript No. (will be inserted by the editor) GDL-II

used in the past AAAI competitions allows to tell a system the rules of arbitrary finite games that are char-acterised by perfect information, but does not extend to games in which players have asymmetric information, e.g. about their own hand of cards, or which involve elements of chance like the roll of dice. Accordingly, contemporary general game-playing systems are not de-signed to play games such as Backgammon, Poker or Diplomacy. GDL-II (for: GDL with Incomplete/Imper-fect Information) is a recent extension of the original description language that makes general game playing truly general, because it allows to describe just any fi-nite game with arbitrary forms of randomness as well as imperfect/incomplete information. This brings along the challenge to build the next generation of truly gen-eral game-playing systems that are able to understand any game description given in GDL-II and to learn to master these types of games, too
