Well Splatoon was one of the greatest games of 2015 and one of the freshest new IP's on any platform for a long time.
Did Splatoon tempt you into finally buying a Wii U?
Maybe it didn't quite tempt you enough to purchase a Wii U but it did get you interested in the prospect of Nintendo's next hardware, The NX? With potentially more fresh new IP's and Splatoon in the future?
Or maybe you had a Wii U sitting on the back bench already and it got you to bring it back out to play?
Myself I had always followed the hype and sales of Splatoon since it launched and whilst not owning a Wii U until I decided around Christmas to take the plunge and grab a new console and the decision came largely around the success of Splatoon and a little bit of XCX, It did not disappoint and some of the most fun I've had in many years came from the Wii U and Splatoon.
