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