Some computer games have an addictive quality which comes from having many “achievements”, frequently reminding players of their progress. Each new achievement gives a sense of accomplishment for the player, and since the steps are relatively minor, the next reward is just around the corner. The term “gamification” applies when a large task is broken into many relatively minor, achievable goals which are salient in the form of points or trophies. We might ask if successful crowdsourcing requires gamification; for instance, is Wikipedia gamified? The answer is actually not straightforward.
