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