I could talk to you about how important this was, what the gameplay and music did that was so innovative and all that, but do you really care? No, you don’t really care. And anyway, I didn’t play it when it first came out. Metroid was only available in Japan, and around that time, I was mostly focused on trying to become an embryo.
My friend once told me a story of an ant farm of his. For a while they went around digging, eating and digging some more. You know, typical ant stuff. Then they started to die, one after another. Bacteria in the dirt of a closed container – or some such.
Finally there was one ant left. It carried the corpses of the others to a particular chamber they’d all dug previously and stacked them. Then it went back about its business until it too died and got no burial but the trash bin.
