Framework for designing and evaluating game achievements

Abstract

This paper presents a framework for evaluating and designing game design patterns commonly called as "achievements". The results are based on empirical studies of a variety of popular achievement systems. The results, along with the framework for analyzing and designing achievements, present two definitions of game achievements. From the perspective of the achievement system, an achievement appears as a challenge consisting of a signifying element, rewards and completion logics whose fulfilment conditions are defined through events in other systems (usually games). From the perspective of a single game, an achievement appears as an optional challenge provided by a meta-game that is independent of a single game session and yields possible reward(s). © 2011 Authors & Digital Games Research Association DiGRA.
