The gameZfestival is back for its fifth edition with three days of talks, international guests, indie game studios, panel discussions, awards and an OpenMic. This year's topic is 'Game Over!' with focus on deaths in videogames. The Festival's Highlights are Jakub Dvorsky from Amanita Design (CZ), Ryan Green from Numinous Games (USA) and Transport Fever's Basil Weber (CH). Our conference track gameZ & ruleZ takes a closer look at motivational systems for non-human games. Yes, animals and robots want to play too! The abstracts you find here. Festival and conference will be accompanied by a playable videogame exhibition.
