Probably depends on the venue. But openers are usually only 5-15 min or so anyway, depending on how many and how the show is structured. Chappelle was disappointing, but not enough to ruin the rest of the show. I was happy to stay for Jon Mulaney’s set which was fantastic.
IMO, on the Game Awards where it was announced, he looked extremely nervous to say much of anything. And he seemed like he was trying to downplay what the game has with his comments on it being a small team working on it. Which I don’t blame him.
