The one-sentence "definition" that should be in italics.

This pattern is a still a stub.

Note: this pattern describes exchanges between people of the items used to play games. See Trading for exchanges of resources as part of the gameplay.

Examples

Using the pattern

Game Element Trading requires Heterogeneous Game Element Ownership and a Multiplayer Game so that different players can own different parts of a game, with typical examples of tradable parts being Cards, Dice, Game Items, Miniatures, and the marbles of Marble Games. For games with Character Development, the characters players control can be the items traded as well. Less common, games using players' positions and the positions of physical artifacts as input to the game, i.e. those using Player-Artifact Proximity, can use these artifacts as the items traded. Regarding Game Items, for these to be meaningful to trade outside the context of a given play session, they need to have some value beyond that play session. For Persistent Game Worlds this may be any type of Game Items, but Cosmetic Game Items and Tools can be useful for players even without Persistent Game Worlds to revisit.

While the type of game element is a first design choice regarding this pattern, where these game elements come from is a second design choice. Game systems can provide them during gameplay through Game Element Insertion (e.g. through Loot) but Purchasable Game Advantages is another solution (seen for example in the booster packs available for Magic: The Gathering). Player Created Game Elements can also be used but risks crashing markets as the values of game elements can become very low if players create too large numbers of some type of game element.

The actual exchange of game elements in Game Element Trading can either be done as Trading inside the game or as Extra-Game Actions.

Games that make Game Element Trading a central part of the gameplay may have difficulties combining this with Ubiquitous Gameplay since this combination either assumes that there are players everywhere of that they can be connected to each other and that the game elements can be traded electronically.

Interface Aspects

This is for example supported through

Consequences

Rather obviously, Game Element Trading create a Transfer of Control of game elements, which may affect the ease of succeeding with Collecting and Gain Ownership goals. If the game elements traded are significantly rare or important for the gameplay at the point of time of the trade, they may become Memorabilia.

While Character Development and Cosmetic Game Items can create Extra-Game Consequences by themselves, the possibility of Game Element Trading adds more types of possible consequences. In contrast, Resource Generators and Tools only produce Extra-Game Consequences when combined with Game Element Trading.

For games where the game elements are physical artifacts whose location is detected by the game system, i.e. games that make use of Player-Artifact Proximity, the use of Game Element Trading motivate players to meet and the games thereby make Player-Player Proximity likely.
