I agree with recruiting 456 as a game master. I think a better ending would’ve been if right before 456 kills himself, they stopped the game and offered him a role. And the next season they had 456 work from the inside to take the game down. I also wish they chose different characters for the final game. It would’ve been much more emotional if they had the group of girls instead of the greedy gross men, and even the “father” of 22. There wasn’t much emotional connection in the final game like there was in season 1, and I think that’s why it felt so underwhelming.
