Metroid fans have been waiting a while for a proper follow-up to Metroid Fusion and Metroid: Zero Mission, but with the franchise's focus on the 3D Metroid Prime titles and the upcoming spin-off Federation Force, it seems that the lack of classic 2D-style Samus Aran adventures is going to go on for a while more. Not wanting to wait it out, several people have put together complete reworkings of 1994's Super Metroid for the Super NES to turn it into new games. NeoGAF member Boney has put together a list of the best new Metroid adventures and invites further discussion about them.
Unless you've been living under a rock for the past 20 years, you should know that the original Super Metroid is widely considered one of the best videogames of all time and for good reason. A masterfully created open ended map overhauled from it's predecesor, with an emphasis on exploration and acquisition of significant power ups. The strong design was accompanied by the creation of a believable ecosystem, gorgeous spritework, wonderful music and too many memorable moments to mention here. It's widely considered the best game in the franchise and every game since then has diverted itself mechanically or design wise to the beauty that is Super Metroid.
So to satisfy you guys before some of you lose it due to deprivation, I invite all of you to be part of GAF plays: Super Metroid Hacks, in which we can find solace in wonderfully designed games made by passionate and talented community that is the Super Metroid scene. These guys have been going strong for over a decade and they show no signs of stopping, making more and more progress and pushing what is thought to be possible to build when handed the keys of the game itself.
There's some interesting stuff happening here. Normally I'm not a fan of underskilled gamers proclaiming that they will make the true Metroid 5 or the real Sonic X-Treme or what have you, but in this case I think that the creators of these Metroid projects have something special happening. There's actual game design talent in action here. Super Metroid Redesign tampers with gravity and rebalances Samus's abilities. Metroid Super Zero Mission is built for sequence breaking. Metroid: Ice Metal focuses on a non-linear design and encourages exploration. Nintendo will eventually take Metroid back to its roots, but the fans can fill the void until then (and more power to them as they do).
