Is anyone aware of any serious(ish) open source game projects using Godot? I very much like the idea of game development as a hobby project and I'd think that contributing something small to an existing project is a better way to learn the ropes than just making an entire game by myself.

If you're just in the beginning stage of thinking about game development as a hobby, I highly recommend just jumping on a project without getting too hung up on the engine. I've shipped hobby games using Unity, RPG Maker, and UE4, but I've also shipped a (crappy) ASCII platformer on top of ncurses. The highest value from the exercise is just jumping in and figuring things out.

That's a preamble to recommending to check out popular open source games like OpenTTD, 0 A.D., or Cataclysm: Dark Days Ahead. None of them use Godot, but they all use game development principles that you would apply in Godot if you were using it.
