"Someone's picky. There are two GBA Metroid games and they both rock. No need to release another one unless you have insanely high standards."
Sure, they rock, but Fusion was a bit too short and way too linear, and Zero was a remake. I get the feeling neither of them is representative of a GBA Metroid's true potential... certainly neither of them is as good as Super Metroid or Metroid Prime. I just have the feeling that if they made a proper sequel to Metroid Fusion on the GBA, using all the untapped potential of Samus' new Metroid powers they didn't really use in Fusion... I think I'd wet myself.
