Most of the time it's based on which games have the most visits. The games on your home page are determined by your interests, what the ALMIGHTY ALGORITHM thinks you might be interested in, and a combination of those two factors plus the games with the most visits that fit those categories. So, if you play a lot of RP games, it'll show you more RP games that you might like, RPG games or games with similar features/subgenres, and RP games that have the most visits. Because of this the ALMIGHTY ALGORITHM tends to promote games that get a lot of Gen Alpha traffic because they're Gen Alpha stuff, since statistically speaking you're more likely to find a Gen Alpha kid on ROBLOX than someone with braincells, thus Gen Alpha games get a lot of visits, thus the ALMIGHTY ALGORITHM shows you those Gen Alpha games because they're popular, since the ALMIGHTY ALGORITHM isn't smart enough to determine what you might be interested in based on your age.
