The Quest (2014). It was a random find on Netflix many years ago. My friend and I checked it out and ended up getting into it. We ended up watching 2-3 episodes back to back. It's one of my all time favorite 'different' TV shows.
"Fantasy meets reality as 12 contestants engage in epic challenges in the world of "Everealm", and compete to avoid "banishment" in order to become the one true hero that will save the kingdom."
Reminds me of another show that I wished wasn't cancelled: The Colony. A reality post apocalyptic survival show, set in LA. I might check out The Quest now.
There's one I haven't heard of in a long time. I was hooked for the brief time it was out. I rember being pumped of potential news of a third season that never came to fruition.
