It's not even up for debate. Super Metroid is probably the greatest game ever made. Remember it's over 20 years old folks. The fact it still hasn't been bettered in 2D is testament to its greatness. Some of you here may not even be old enough to debate this fairly. Platforming, exploration, music, upgrades, isolation, it nailed everything perfectly. Samus in Prime is missing so many of her abilities and agility it can't possibly be better. Where's the screw attack, wall jumping, speed booster, space jump, shinespark? Even things like the grapple beam like some of her other abilities are severely neutered in Prime. It doesn't have an ounce of its ability from Super Metroid.
