The constant new ideas and then remixing them is a core foundation of Nintendo's game design and it's what sets them apart from the wannabes. Linger too much on any one concept and it gets stale. Introduce new ideas and then bring them back in a completely different context later, and you have a sweet tasty treat.
I was really feeling this distinction while playing the Last of Us, which thoroughly disappointed me. The game runs out of creativity very early on and recycles the same gameplay blocks over and over. It's clickers again, it's ladders again, it's rafts again, it's bandits again, it's clickers again, it's ladders again, it's rafts again, etc etc etc. When suddenly the game had a hunting scene with a deer, I was like... hey wow I'm invested again -- why did it take so long to switch things up? (This happens in like, the last 3 or so hours of the game)
I don't have a problem necessarily with a game sticking to its basic concepts, but the whole reason why Mario games are great is that they constantly keep you off your guard and make you learn new concepts, and then chop and screw them to throw you off guard again.
