That's funny.
Wanna know why? DmC never went through as much work as past games did.
It had a formula already layed out for it. A gameplay formula that the four DMC games, DMC 1, 2, 3 and 4 evolved.
Let me give you an analogy to illustrate my point more:
DMC 1, 2 , 3 and 4 are scientists who worked hard to create something called "Gameplay".
They failed alot, and there was alot of explosions. Scientist 2 and 4 got hurt by the explosions.
And after alot of work the four scientists managed to make the object known as "Gameplay". They even wrote down receipe/formula on how to do this.
DmC the scientist came and took the receipe. Unlike DMC 1, 2, 3 and 4, DmC did not fail when working on making the object "Gameplay".
Because the scientists known as DMC 1, 2 , 3 and 4 had left behind the receipe/formula in how to achieve the object.
Hurray!
P.S You know of Metal Gear Rising? It was nearly cancelled because Kojima's team didn't know what to do with the gameplay.
EDIT:
Here is Kojima P's Hideki Sasaki explaining the issue they had with Metal Gear Solid: Rising (before PG took over):

^ This is what happens when you start at scratch
Or how about you take a look at the gameplay of Heavenly sword:
Another scratch game
I'll say this much. Hire Vigil Games and they prolly could have achieved same degree of sucess like Ninja theory or perhaps more.
