The best multiplayer moments are not about winning -- they are about winning together and having someone who saw it happen.
Relatedness, the third pillar of Self-Determination Theory, is the need to feel connected to others -- to belong, to care, and to be cared about. In multiplayer gaming, relatedness is the invisible force that makes cooperative play more satisfying than solo play, that turns random matchmaking partners into friends, and that keeps players logging into games long after the content is exhausted. The game becomes the social venue, not the product. Relatedness explains why many MMO players describe their peak gaming memories not in terms of loot or progression, but in terms of people -- the guild that became family, the raid team that overcame impossible odds together, the stranger who helped when no one had to.
Example
Destiny 2 raids are designed to require six-player coordination that builds genuine bonds through shared struggle. Journey's anonymous multiplayer creates wordless emotional connections between strangers. Sea of Thieves is mediocre solo but magical with friends because the game is a vehicle for shared stories. It Takes Two literally requires two players and builds the entire design around cooperative relatedness.
Why it matters
Relatedness is the most undervalued design pillar in gaming because it is harder to engineer than competence or autonomy. But games that nail it create the deepest engagement and longest retention. The players who stay are not staying for the content -- they are staying for each other.
