Here are the ones I listened to yesterday:
This one was interesting. The main key point I got from the video is that, once they lost the original developers, the whole direction of the game shifted from exploration to adventure for game II, and for game 5 they had a team that had no morale and the game completely reused and rehashed old ideas, making the series lose its charm.
I'm currently in the process of watching this one, at about 45 minutes in. So far what shocked me is, while I knew Kojima had a lot of knowledge of movies, I didn't realize his father would make him stay up late regularly to watch many movies, his brain almost like a sponge for American movie culture. Also I didn't realize the Metal Gear II on MSX 2 was so advanced for its time. Will keep watching this attentively.
