Never tell yourself your idea for a game is too wanky or obscure to succeed.

There is an actual, published tabletop RPG based on No Exit – yes, the Jean-Paul Sartre play – and as far as I’m aware it sold quite well.

I’m holding a copy of it right now.

It is literally impossible that your idea is more inaccessibly pretentious than that.

You must not forget that your target audience consists, in main, of huge nerds.
