I believe Retro have nothing to do with Other M, they just did the Prime series. An internal Nintendo studio (R&D1 I think) did the others, and are running the Other M production. Super Metroid is available on Virtual Console on Wii if you want to check it out, it's a lot of fun.. yet quite retro in a lot of ways. There's no tutorial for example. If you do check it out and you get stuck, hit up Video Game Cheats, Reviews, FAQs, Message Boards, and More - GameFAQs for assistance.
