Roblox

This is a personal recommendation. There are various types like obstacle courses, horror, escape rooms, and grindy ones. I personally enjoy obstacle courses and tend to go for parkour-style games, but what I'm currently hooked on is something called 'Animal Hospital (Anomaly)'. There are creators on YouTube who mainly post Roblox content, so you can enjoy it by watching their videos. I don't think it takes up much space, so I'd recommend it even to those who might worry about storage limitations.
