"About" means related to, and "have been about" in this context means have been related to. So in the context of the video, he is saying that the last ninety-seven hours have been related to or focused on this game. This means that the total ninety-seven hours involved preparing to get to this point in this game. Ex: What is this movie about? Ex: This evening has been about getting to know our neighbors better.
