In pencil and paper games and computer and video games, an item is an object within the game world that can be collected by a player or, occasionally, a non-player character. These items are sometimes called pick-ups.
Items are most often beneficial to the player character. Some games contain detrimental items, such as cursed pieces of armor that confers a negative bonus to the wearer and cannot be removed until the curse itself is lifted; the means to do this may be costly or require a special item. Some items may also be of absolutely no value to the player. Items are especially prevalent in role-playing games, as they are usually necessary for the completion of quests or to advance through the story.
Sometimes certain items may be unique, and only appear once at a specific location, often after completing a particular task. Other items may appear frequently, and not give a big bonus alone, but when many are collected. Games may differ on how the player uses an item. Some games, many in the Mario and Sonic series, an item is automatically used when the player character comes into contact with it. There are also games, such as those in the Streets of Rage series, and the first Prince of Persia games where the player character may walk over an item with out collecting it, if they do not need it yet, and the player must push a particular button for the player to collect it, but it still used immediately, when the button is pressed. Other times, some games, like many role playing games, an item can be collected either automatically or manually, but will not be used immediately, the item can be carried around and used manually either straight away if they wish or at a later time when the player needs it.
Items often come in various types and in most games where items are collected, they are sorted by these types. In RPGs, an item inventory is a common UI feature where one can view all the items that have been collected thus far. Often, these are sorted by categories, such as "equipment" or "Potions." In other game genres, the items may take effect as soon as they are obtained.
In many platformers, like Sonic the Hedgehog and Super Mario Brothers, items are scattered throughout the Level in Item boxes or on their own. Many video game items are common to all games.
