I understand what your intent is in saying this, and I agree with the intent, but for onlookers, you don't really need a lot to make a good game and this would likely be just fine. I don't actually know if it's possible to ship GL games on modern consoles now that it's in-fashion to have your own proprietary graphics library. That said, the way Google has factored the back-end of the renderer, it won't take a PhD to target one of those GPU APIs.

Aside: GL is still a good practical choice for games built by small teams.
