The most polished game on the system
When the Wii controller was first introduced in 2005 at Tokyo Game Show, Metroid Prime 2: Echoes was a showcase game for how the controller would work in a variety of ways. This is the way how Metroid Prime 3: Corruption would control. By using the Wii Remote's IR sensor for aiming and turning, and the Nunchuck's thrusting and pulling action, it provides for a great, yet subtle and innovative experience that most developers on the console have yet to try. The best control method is only gained by changing the settings in the in-game menu however, which provides for more accurate controls. A problem does lie in turning, where in some situations you might be forced to switch the Morph Ball mode just to turn quicker. But overall the controls feel and control great, just like the graphics.
The Metroid Prime series has always been known for its' great graphics and art design, and this game is no different. You visit a variety of worlds, and the creatures are more detailed than ever. The lighting effects especially make the game feel more vibrant and less dreary than Metroid Prime 2. The game also runs in 480p and 16:9, like most quality Wii titles. However, once again, the game's 16:9 support does come with black bar support as well. They're small, but once again makes HDTV owners wonder why Nintendo can't provide pure 16:9 support all the time. Some of the effects are also not as polished, as you some effects look like they were taken out of a cheap action film.
A main complaint about the previous 2 Metroid Prime games has been the music. They have been of much discussion over the past few years, and Metroid Prime 3 does seem to quell this argument somewhat, but mostly only to gain a slight favor with most people who've played the game. The music is very elegant and dramatic at the same time. However, past the intro theme, you won't be humming any of these tracks 5 years down the line. This game also has full voice acting for every character, besides Samus of course. The voice acting is well done, although not quite as well as some other games. However, given Nintendo's use of, or lack thereof voice acting in their games, it's easily the best.
The game provides multiple difficulties, one you have to unlock, and multiple things you can get by doing certain things. You can get Green Credits to trade with your Friends to help unlock music tracks, art galleries, and dioramas. To get everything, you need to beat the game and collect everything on every difficulty, which Retro didn't make that hard to compensate. Metroid Prime 3: Corruption was the best game released out of all those trilogy games last year. It gives you everything you could ask for out of this franchise, and maybe a little more. Well, except for being 2d of course.
