"Super Mario Galaxy" is an incredibly fun and addicting game! The levels can be very easy in the beginning, but they slowly get more challenging while still being fun. The graphics are very good for the Wii system. The Wii seems to get shorthanded with graphics in a lot of games, but not this one! Yes the graphics are not going to be like the XBox, but in "Super Mario Galaxy" the Wii's graphics are outstanding! This game clearly took in mind the Wii's capabilities and it shows (in a good way)! The opening cutscenes were especially beautifully done.Speaking of cutscenes, one of the down sides is the beginning. There are some long cutscenes that you can't skip; some of the cutscenes tell the story (i.e. Bowser kidnaps Princess Peach) while others explain how to play (while simultaneously furthering the story). Not bad if you: a) want to know the back story; b) are a younger kid; c) new to video games or Mario games. The cutscenes were okay, but after a few I really wanted to play the game!Now to the gameplay. I found the gameplay in this game to be very inventive. The premise of the game is that you are on the Comet Observatory. On this Observatory there are domes that lead to different galaxies. You start with only one dome open, but as you collect stars more become available. Each dome contains a certain number of galaxies that have their own gravitational system. Sometimes you can walk upside down on a planet or you could constantly be being flipped upside down or right side up to complete a level. It can be confusing at first, but once you get in the swing of it, it's so much fun!The power ups are pretty good. There are the some traditional power ups (i.e. Fire Flower), but also some new ones like Bee, Boo, and Spring Mario. I like Bee Mario (you can fly for short bursts of time and crawl on some walls), but I HATE Spring Mario. With Spring Mario you turn into a spring and have the ability to jump really high. For the longest time I could not get it, but now I sort of do. Spring Mario is kind of sensitive to the controls, but if you keep on moving and know where you want to go before you jump--it's a bit better. You just need to practice.The controls are good. I don't find myself worrying too much about the controls during the game, except when you are Spring Mario or swimming. Thankfully there are not a lot of swimming stages. When you are swimming, the controls are inverted (which is not a huge deal), BUT if you need to turn around you have to make a big circle. Not to much of an issue...except if you are underneath something and need to get to air so you don't die. It gets better with practice, but it's still awkward.This game really uses the Wii motion technology to its advantage. You use the control stick on the nunchuk to walk, A button on the remote to jump, Z button on the nunchuk to crouch, and point the Wii remote to collect star bits. Collecting star bits is important because they can open new areas of the game (if you feed them to Hungry Lumas) and they can be used to stun enemies (point and press the B button on the Wii remote). There are some moves like the Spin Jump that also effectively use the Wii remote and motion technology.While this game is marketed as a 2 player game, it's really more like 1 and a half player game. See, when you add a second player they don't play another character (i.e. Luigi or Toad). They take over collecting stars and shooting star bits and stopping enemies. While they can also make Mario jump or spin in mid-air after jumping, the most effective use of the second player is collecting star bits and stopping enemies. While this is not as fun for more seasoned video game players, it can be fun for younger kids or people new to video games. It could also be helpful when there are a lot of enemies to deal with.If all of this were the only things to be taken into account, I would give this game only 4 stars. HOWEVER, the thing (in my opinion) that makes this a 5 star game is the music. The music is SUPERB! Great graphics, fun worlds, awesome gameplay is all tied together with really epic music! In my opinion the music seals the deal in making this 5 stars! Great game and very addicting! A "must buy" for any Wii owner...especially since this game is now a Nintendo Selects and only $20! In my opinion, this was money well spent.
