I think that API looks reasonable. I'd do it in 'skellington' for now and
let game creators play around with it before it becomes 'official'.
My understanding of namespace packages is that all the pieces that use it
have to agree on what is a namespace package, so we can't make pygame a
namespace package, because we already use it as a regular package. My
experience with the 'backports' namespace package is that it's not worth it
anyway - when it goes wrong, it's horrendously confusing and tricky to fix.
So as and when it becomes a package, I'd just let people import it as
'pygame_resources'.

I think it does give some stuff, e.g. its data loading routines know about
zipped egg packages. However, I also think eggs should be avoided.
Setuptools (which pkg_resources is part of) has a particular way of seeing
packages - for instance, it can handle different versions of the same
package installed in the same environment - but that view conflicts with
the model most Python programmers now favour, based on pip+virtualenv. I
think setuptools makes sense if you buy into its view entirely, but if you
don't, it makes things opaque and complex for little apparent benefit.

That's quite neat. I disagree with the way it privileges the launcher
script, which I often don't have in a consistent relationship with the data
files, but I like that you can use a package directory. I would probably do
something like this:
from pyglet.resources import Loader
resources = Loader('@' + __name__ + '/data') # resources in mygamepkg/data
