MODERATOR NOTE SMG2 IS NOT RELEASED IN EUROPE UNTIL THE 11TH JUNE, PLEASE POST ANY SPOILERS IN A SPOILER TAG...
THANKS LEE
How in the heck does this not have an official thread yet?

I just got the game myself a few days ago. It's even more fun than its prequel. Similar gameplay from the previous game (and other Mario games) returns, better than ever before. I really like that Yoshi has been added, something really felt like it was missing in Mario Galaxy 1 and Yoshi was just that. He even gets some power up items of his own. Nintendo really got creative when coming up with Yoshi's controls such as using his tongue to grab onto things, and his power ups are almost as cool as Mario's. Speaking of power ups, all of the power ups present in Super Mario Galaxy 1 have returned except for the Ice Flower which got replaced by the Cloud Flower and the Rock Mushroom. I knew already after just a few stars that I was in for a fun gaming experience. For those who don't have the game yet, BUY IT! If you don't have a Wii yet, buy one and then buy this game. It's worth it!
After being out for only about a week, Super Mario Galaxy 2 has already been referred to as the new standard of platformer games, earning a perfect 10 at gamespot's rankings (an EXTREMELY rare accomplishment!) and it's another fun addition to the legendary "Mario" series. What do you like/dislike about it so far? Anything stuck out as particularly cool or difficult yet? I personally feel that it deserves to have received its perfect 10 score because while I wouldn't give it a perfect 10 myself I still find it to be just as great as it was hyped up to be and it's an incredibly fun game, totally worth buying!
Feel free to talk about anything related to Super Mario Galaxy 2 in here, just don't forget to include in your post why you have that opinion rather than just stating it.
Let's have a great discussion about this really great game.
