Achievements and Achievement systems are recognized as important elements to increasing the profitability and success of games titles. Achievements can influence a player´s buying decisions and can even increase a player´s motivation to continue playing a game.

To this end, this paper will consolidate current knowledge and provide an overview of the features of today´s Achievement Systems, exploring the common features of the most popular systems and highlighting points of differentiation designed to better engage players and increase distributor revenue.
