Spherical planets were are you?

I'm having a blast right now with Mario Galaxy 2 but after days playing it i have noticed something strange. Were are the cool spherical planets available in the original Mario Galaxy? I remeber how awsome it was staring playing the first stage and discovering you could walk all the way dow the planet and find routes and different things that weren't on the top side. From what i played so far in Galaxy 2 there arent stages like this.

There are you're just not seeing them.

They had sperical planets on the first level (second if you count the tutorial level).

They're in there, but there's definitely less of them.

It's for the best.

At first it was cool seeing all the things you can do with gravity, but it can't go much further than that. I found the first Galaxy to be a bit boring at times because all you would do is go from one planetoid to the next. It got old to me.
