The id software game Return to Castle Wolfenstein is being ported to the Quest and should show up on DrBeef's github soon:

But on their Youtube channel they recently posted some nice streams on how to make avatars and stages for Hubs in Blender3D:

Edit: oh and an article on the difficulties to get desktop VR working on Linux:
