I rewrote this article, converting the lists into paragraphs and adding a bit of information, as well as spoiler and stub tags. I can't really see a good way to organize this article to divide spoiler from non-spoiler information, as almost everything here spoils the game in one way or another. If someone has any ideas on how to organize this better (especially keeping in mind that the other half a dozen Metroid games should be added), I'd love to hear it, as I'm at a loss.
