Rec Room is a free social virtual reality game from Rec Room Inc, first released in 2016, where players create avatars, build rooms and hang out together in shared spaces. Its join notification tells players in a room that someone new has arrived, a small but important cue in a game built around meeting people. As gameplay clips, streams and short edits spread online, the sound became familiar even to viewers who had never played, and creators now reuse it as a shorthand for arrival, welcome and a lobby coming to life.
