The aim of the 13th annual European GAMEON® Conference (GAMEON®'2012) on Simulation and AI in Computer Games, is to bring together researchers and games people in order to exchange ideas on programming and programming techniques, which will be beneficial to the gaming industry and academia. Secondly it aims to steer young people into this industry by providing how-to tutorials and giving them the opportunity to show their ideas and demos to the gaming industry. The conference will concentrate mostly on the programming of games, with special emphasis on simulation, AI and fuzzy sets, and physics related computer graphics. Next to that, all of this will be fused in the topic of computer game design in stand-alone and networked games. Software providers will be able to show their latest packages and give hand-on tutorials for the participants.
