In video games, a collection-fest or collectionfest is a game where the majority of the gameplay involves collecting items to advance the game; in particular, the term is often used as a complaint when a game features a plethora of items to collect that have little or no use to the player, other than as an arbitrary lock-and-key system that limits progression. Usually, the game would have one major item that must be collected in each level to proceed through the level, and a number of minor items that can unlock certain bonuses.
