I didn't regret spending the money. I've only gone through it once so far. I haven't actually tried it yet, so I just have a general idea of what's there, what kind of functions there are, how games are made, that sort of thing. I'm going to connect an auxiliary monitor and try it out myself as I go through it 2, 3, and 4 times, gradually internalizing everything. The reason I was able to listen to the end was because the instructor's pronunciation was clear and the content was compact without any unnecessary information. I'm sure it will be a new experience to listen to this lecture again when my game programming skills have improved in the future, right?
