To add to the other comments: Free exploration, community and YouTube. The way developers iterate on gaming concepts and allow players to be part of the evolution seems to be appealing. Tower Defence games are one example, where there are many implementations. The games evolve and change, sometimes rapidly, and the players and community come along for the ride. Then another new Tower Defence game comes along, a YouTuber showcases it, and they all go try out that one. Then the old game gets a big update, and they go back and try the old one again. The games are often very similar to each other, or knock-offs of commercial games. They often use irreverent meme culture visuals and sound effects, which makes the games seem fun and disposable. None of it is taken very seriously, on the surface at least. The key here is the community - all these games and their friends are on Roblox. They don't lose their friends if they switch games, and games are free to play, so their friends can easily join them without having to ask their Parents to buy the game for them! When you look back at the early Roblox games, it's remarkable how primitive they are. However when you view todays games, it's equally remarkable for sophisticated and impressive the graphics are!
