Have you tried modding or mapping? In high school a large part of my life was spent around learning to map for various games because it felt like a way I could actually give back to the community I was a part of while exploring the creativity of it.

I enjoyed making the content and seeing reactions to it and trying to one up myself then I did actually playing the game. In fact it gets to a point where you've seen enough behind the curtain that it loses a lot of its charm.
