Also, for those whining that the art isn't changing a lot recently, and that brings up the old games that changed continuously:
These changes came from the limitations of the consoles. They tried each time to make it better and better with the limited capabilities. The art changed because they were able to squeeze more and more juice out of them. Now, the consoles are very powerful and there is almost no limits to break. And for the Mario games, well, it can almost be said that the ceiling have been found. Still, look at the backgrounds off NSMB U, they are gorgeous and very much alive. In my book, this count as an amelioration.
Also there are MUCH MORE moving platforms. And they are not only moving from side to side and up and down. Again, an amelioration.
Shy Guy? How did I return to that?? I was a Koopa? ... AWESOME!
