Games like these can be successful, for example cats and soup is a game that I see people playing, it involves the cats making soup and you selling it, with selling it you can upgrade your food. Candy Crush would also be another game that is successful, all you need to do is line the candies and you get points. A lot of people like games like these because they don’t involve you going out into the wild and finding stuff to upgrade your characters like in Genshin Impact, and it’s not difficult to understand how the game works. I hope this helped, if it didn’t sorry.
