As of August 2020, at least 20 games had been played more than one billion times, and at least 5,000 have been played more than one million times.[112] TechCrunch noted in March 2021 that Roblox games are largely distinct from established traditions in free-to-play video games, finding that successful Roblox games were geared towards immediate satisfaction, and finding that the addition of tutorials significantly decreased player engagement, contrary to established wisdom about free-to-play games.[113] Companies have used Roblox as a platform for advergames promoting their products.[114][115][116]
