Or just even on, like World of Warcraft, they had a great relationship with QA in that they built out a full raid team to do the raids. And then you’re not only, like, looking for bugs, like, “Hey, the dragon was supposed to fly and instead it just, like, sunk through the world and the game crashed,” which would happen.
