I thought that this was a very good game. I had a lot of fun playing it. The only thing that I didn' like was that they repeated certain bosses a lot, such as Boom Boom. Other than that I thought it was a very good game overall. And if your planning on doing a 100% playthrough of it, good luck!
first off the 3D is so strong your eyes need alot of rest and make sure to play in a WELL Lite room. as you can tell by the title. The Stages on this game r the best ive seen ever. ON any game..they are all put together nicely. the second half of the game..the stages are harder than the 1rst half. Story...you know mario is not much on story.other than bowser takes peach..play a luigi at the start of the second half. music..prepare to have the music in your head for a long time. even the final battle with Bowser is awesome with the music. the game can take alittle while to beat..all the 200 lives you get in the easy half of the game will almost be gone on the second half. your hands will hurt after dieing alot.not too many items as mario galaxy 1 and 2. ..I think alot of people will enjoy this..and expert players will enjoy the second half.
From my 7 year old:
It was fun. I liked all the levels. I liked how after I won all the first levels with Mario, you got to go back and do the levels again with Luigi, but the levels were different. I found Princess Peach. It always kept me playing and not wanting to put it down.
