I like how the play can be referenced. It is always nice when worlds in stories contain their own stories, rather than piggybacking off of stories that make no sense existing in that world.
What's up with the whole "The hero and demon lord must fight!" mentality? It's like the world thrives on the thought of bloodsport.

I hope that is not what's happening here. I can already think of two series that pulled it off well with excellent deconstructions:
The Legend of the Sun...
At least casinos have that nice glitz and glamour feel. You should never play to win, but rather pay to experience the rush.
That's why it is important to set a VERY hard limit, so you don't get carried away.
