Part of the success can be attributed to the lack of good options coming to the Wii U in the last couple of years. So, in some ways, it faced a lot less competition than most other games.

Didn't help games like Starfox Zero, Ultra Smash, or Paper Mario Colour Splash.

Those were the other options which pushed people towards Splatoon.
