How are games like Closure chosen?
Every game is described by the tags Steam players vote on it. Rare, specific tags such as Platformer, Puzzle, Experimental count far more than catch-all ones like "Indie" or "Singleplayer", and each game is scored on how closely its whole tag profile matches Closure's. Popularity never affects the ranking.
