The thirteenth conference on Advances in Computer Games (ACG13) will be held in Tilburg, the Netherlands, in conjunction with the 19th WCCC and the 16th Computer Olympiad at Tilburg University. The conference commences on Sunday November 20 at 08.30-12.30h and will take place on three consecutive days. The conference aims in the first place at providing an international forum for computer-games researchers presenting new results on ongoing work. The recent successes of the ACG Conferences and the Computers and Games conferences have encouraged the organizers to widen their scope and therefore we encourage contributions on Robotic Pool and Snooker as well as on virtual and video games and modern board games. So, we invite contributors to submit papers on all aspects of research related to computers and games. Relevant topics include, but are not limited to: (1) the current state of game-playing programs for classic and modern board and card games, (2) the current state of virtual and video games, (3) new theoretical developments in game-related research, and (4) general scientific contributions produced by the study of games. Also researchers on topics such as (5) social aspects of computer games, (6) cognitive research of how humans play games, and (7) issues related to networked games are invited to submit their contributions.
