well, I think the Hollywood Elites stopped making them because they discovered a new kind of dystopian reality show to make.
that was always the next step of the obsession with ritualistic dystopian plotlines where innocent people have to compete for their lives in some twisted universe where a few sickos rule over everyone.
it only makes sense, because if they can't really do it in real life, then they need to recreate their fantasies somehow.
there's a new kind of horror show pornography and it's the games regimes play with people's lives.
the rewards are really just "congrats! you survived the torture!"
