Manyland is amazing, I totally recommend it to anyone of any age. their endless possibilities.
You can draw and code your own areas/games you can draw just for the fun of drawing and share it at the spawn area, you can post on forums, or as they call them "writable" you can be whoever or whatever you want. you can be any creature any person with any style. when I played this game I pretty much abandoned any other games to make time for it, it also has the best real-time chat ever, it feels like I'm actually talking to people face to face despite me typing words on a screen. the possibilities are endless, you can make tons of new friends. make your own friend group or join someone else. the only flaw this game has is that everyone in the world doesn't play it.
Really fun game where you can meet lots of other talented people, create many areas that are completely customizable from start to finish! The community is really nice aswell, and if you aren't that talented, you can find and use many other peoples creations! would definitely recommend atleast trying once. :)
