Think of video games, and you'll probably think of something competitive.
Some of the most popular titles in the world, such as Fortnite and Call of Duty, are focused on outgunning, outrunning or outclassing opponents.
But, as Josef Fares and his studio Hazelight have shown, that's not the only thing gamers want.
His latest, Split Fiction, is a collaborative experience where two players work together to solve puzzles and beat obstacles.
The adventure game has received rave reviews, sold one million copies in 48 hours and is currently among the most-watched titles on streaming platform Twitch.
It's not a one-off. His previous title, It Takes Two, featured similar "couch co-op" gameplay and sold 20 million copies and won a Game of the Year Award.
What draws players to these friendlier experiences?
