Hahaha, I think I've got a game you'll love.
It's ten years old and still in development.
Now it sounds old, but it has a very tight community.
It really isn't a well-known game.
It's called "Shores of Hazeron".
http://www.hazeron.com/Shores of Hazeron is a space exploration vidya game where you either create an empire, or join an existing one.
I highly recommend you check it out. It's massive, multiplayer, and online.
Oh, and it's being developed by one man. So I guess that makes it an Indie game too.
