One of the best games ever made!
The Graphics are really superb. It was a big leap to 3D but everything looks great and all the landscapes are beautiful looking out of Samus' visor.
The Sounds are amazing too and they make you feel like you're actually in there, trying to kill the monsters yourself.
The Gameplay is just magnificent though. The controls react perfectly and are mastered in about half an hour and you can roam the landscapes freely once you have the weapons to get past each door. The bosses are great too, they are hard but simple when you know how to kill them and the atmosphere is so tense due to the realistic graphics and heart pounding music.
You can play this game for hours without getting bored for a single second and you can spend even longer looking for all the items.
Altogether, this is a great game and a must have for any gamecube owner and a good reason to get a gamecube if you don't already.
