The Basement Brothers are a good channel. I enjoy the quality of their work and what they are aiming for with their videos.
I think I first became aware of the games on Japanese PCs when I discovered that Metal Gear 2: Solid Snake on the MSX2 was the actual Sequel to Metal Gear and not Metal Gear Snake's Revenge. And that was when I played MGS 3: Subsistence.
I didn't know Lagoon was a Y's Clone and on the X68000 originally. It does explain a lot. As a child I recognized it had some odd design choices.
