Well, it took me about half a decade, but I finally finished Super Mario Galaxy 2. I really liked the first one and this is a lot more of the same. There's a bit of "been there, done that," in my opinion of the game. A few new additions have been added, like being able to ride on Yoshi and use his tongue like a grappling hook. But, for the most part, this is pure 3-D platforming at about the best it will ever get. Which is to say, yeah it's pretty good for a not-so-deep game.
As with the original, gravity and orientation are used to mix things up and give everyone in the room motion sickness. Once again, plot is an afterthought that doesn't serve to motivate players to go farther. In the end, I don't think I am an OCD enough gamer to keep going in an attempt to find every secret and collect every star. I'll leave that for the youngsters who seem to have all the time in the world. Those, jerks.
