I know a lot of people of 16yo who were playing on a minecraft server, or who were running a minecraft server, and now I'm 19, and I still have a friend who plays minecraft, as I'm doing.
You can still play this game while worrying for your future, no matter what game you play.
Minecraft is still suitable for your age.
I don't know a lot of people to play with tho, except on some servers, and I rarely vocal with people.
Just find where to play, pretty sure you can find people to play and talk with
