Crossover Wiki:Concept crossover

A concept crossover refers to a work that is part of a series that it only has type 3 elements of, like gameplay, while having type 1 elements from other series, like characters or settings. This is considered to be a type 3 non-directional link between those series. Note that if there are multiple series with type 1 elements, and they interact, there would be a type 1 indirect link between those series.

If there's a link with a type that's stronger than type 3 to a work that's a concept crossover, it would only be considered to be a link with the series with type 1 elements in the concept crossover. If there's multiple series, it would only be a link with series that have elements in the link. If there's a type 3 link to a work that's a concept crossover, it may be considered to be a link with the series with type 3 elements if those elements are in the link.
