Achievement (video games)

In video gaming, an achievement (or a trophy) is a meta-goal defined outside a game's parameters, a digital reward that signifies a player's mastery of a specific task or challenge within a video game. Unlike the in-game systems of quests, tasks, and/or levels that usually define the goals of a video game and have a direct effect on further gameplay, the management of achievements usually takes place outside the confines of the game environment and architecture.
