Everything about this game is perfect: its awesome sound, its breath taking art, the perfect control, the beautiful...
1. Gameplay: The gameplay is as good as it gets. Walking is controlled woth the nunchuk, obviosly, but some fun things you do with it the remote to move Mario are great. Some of them include Ray surfing, rolling a ball, flying, and shaking it to climb vines. The primary attack system ( spin, which you do by shaking the wii remote) works well all the time. Jumping through platforms affected by gravity rules, and all the launch stars make it fun. The suits, oh, they are extremely awesome, and serve their purpose perfectly. Gameplay is defintely the strong point of this game, and they should make more game with this mechanics .
2. Graphics: Think state of the art ( stole from gamespot :) ). The visuals are excellent, and this shows what the WIi can do. Everything runs smoothly, the characters look great ( specially bowser) and the galaxies are not the same, NONE of them look alike and are great to play. Another strong point of the game.
3. Sound: What TP did not do in orchestrated music, SMG did in a huge and awesome way. The sound is great, and sometimes, you will want to play this game only to hear the music. Nuff Said.
4. Value: They main storyline takes about 6 hours to complete, but to actually complete all the game, you are looking at 20-25 hours of gameplay, and you can use Luigi!!! Period.
5. Difficulty: Here´s the only complain I have abotu this game. Its just a lil to easy, but the replay value keeps, sucking me in, so thats why I put the difficulty in just right. If you look for a fiar challenge, you will do good in picking up SMG.
6. Tilt: It completely changes the way some platformers should be played, and the gravity is the best addition to this game. If nintendo did more games with this in mind, they would make millions.
Overrall, is the best game of all time , just behind Ocarina of Time(http://www.gamerankings.com/itemrankings/simpleratings.asp). Trust me, 50 bucks is nothing to play this masterpiece over and over again until another incredibly amazing tittle like this comes. Dont hesitate, buy it.
