There is really no point in reading this review, you already know Metroid Prime is one of the greatest games around, or that's what everybody else thinks (including me). But read on if you want to. The following is just my opinion. Metroid Prime, Samus to the Gamecube as Master Chief to the Xbox. Simply put, the game excells on all levels, it's near perfect and one of the best damn single player games created for the Gamecube.
The graphics are jaw-dropping; amazing with both technology and art direction. The game is highly detailed and it runs smoothly even when half a dozen missiles are soaring straight for you. Even when you are fighting a multitude of enemies that are constantly firing at you. Even though the game has fire worlds and ice worlds, they are both represented with style. The fire world feels a tad weaker but it's probably from the lava and the brown cavern walls. The ice world (along with all the others) feels realistic and immersive. The enemies are portrayed stunningly and all look amazing. There are little details that are noticable and add a sense of realism to the game, most specifically when there is a explosion near Samus, you can see her face reflected on the inside of her helmet.
The sound is spot-on amazing, the sound effects feel real and mixed with the graphics, makes the world feel truely alien. More so with the sounds the enemies make, when they scream and howl and even their projectiles (missiles, energy blasts etc.). The music is faint, it doesn't get in the way and most of it fits the game. It adds a sense of excitement when it changes and more so when you're fighting enemies. The music quickens and it makes you feel tense, nervous with the sensory overload of all that's going on.
The gameplay is where it truely shines. The control is, simply put, perfection once you get used to it. It feels tricky but after the first hour or two, it becomes like second nature. When you actually start playing, it feels claustrophobic in the suit. You can only see what Samus can see. This makes it feel different, but in a good way. With the lock on, combat is a bit easier but still challenging when you face new enemies. The upgrades are many and all provide a better experience. The different weapons utilized make the combat that much more fun. The only problem, in my opinion, is with all the scanning. To get 100%, you have to scan everything atleast once. That includes bosses (which you're going to scan them anyway to figure out how to beat them) and one time scan data. There is no multiplayer but this game will be in your Gamecube for a while.
In conclusion, you really should try this game. It's one of the best for a reason and it's one of the best gaming experiences in the Gamecube era. It didn't win Game of the Year for just looking pretty.
