So I never played Super Metroid until I got a Wii. I had played Metroid, Metroid II, all three Primes, Fusion, and Zero Mission, but never Super Metroid. I don't know how I missed it as a kid, but I did. I finally booted it up around 2008, feeling like I owed it to myself to play what was generally considered one of the greatest games ever made. I'm so glad I did.
Like its SNES cousin, The Legend of Zelda: A Link to the Past, Super Metroid didn't do anything revolutionary; it simple perfected the formula. With amazing level design, epic boss battles, superior graphics, precise controls, and an emotionally powerful story, Super Metroid has it all. In my opinion, it's the best game in the series, and one of the two best games on Super Nintendo.
Happy birthday!
