Nope. But it's def up there. Too 5-10 ish.

I'd say the Kojima/konami thing was huge.

And ff7 remake. Battlefront no story mode. shenmue 3. Basically Sony's e3.

Hmmm it was on pc too... You know, the platform with the 1.7b installbase, so probably most of its sales come from it! I'm not pointing out that  detail to downplay  its sales but just to show that the comparison is misguided and unfair!

Good question... But only because it'll strike up good conversation. But the answer to the question is absolutely, unequivocally NO!!! Splatoon really isn't so great. It's just sold to a market that's starved for something fun to play.

On the Nintendo side of things, most definitely. In all of gaming? Konami.

nah, splatoon came out 1-2 years too late. as great as the game is, it didn't really inspire hw sales as it released when the console's reputation was already tanked. For such a successful new ip and type of game for Ninty, it should have sold more consoles, but again no one wants to touch wi u when they see its bleak future.

Even on consoles that did get solid 3rd party support, Nintendo developed/published games always stole the show so I highly doubt the presence of 3rd parties on Wii U would somehow negatively affect Splatoon sales.

The gamers were starved argument doesnt hold much weight either since games like Wonderful 101, Pikmin 3, Wind Waker HD, Tropical Freeze, Hyrule Warriors, Bayonetta 2, Captain Toad, Rainbow Curse all sold much lower. The only games that have sold better on Wii U are 2 Mario platformers, Mario Kart, Smash Bros and the heavily bundled Nintendo Land.

Mario Tennis and Amiibo Festival aren't doing too hot though!

Not even close.

The biggest Nintendo stories of 2015 would be the death of Satoru Iwata, the partnership with DeNA to launch mobile games and the reveal that they were working on NX.

But I'd say that Splatoon would be one of the surprise games of 2015, along with Rocket League and a few others.

You have to wonder how history will look upon this year. Everybody is saying Konami is the big story but if Kojima comes out and hits a home run in two years or so there's a chance many forget about all this by the end of the decade. Whereas Splatoon could be the gen's highest selling console game in Japan, the game best out CoD and Halo in multiplayer awards, and very well could have changed the landscape for the genre. We simply don't know yet. If Splat2n flops, yeah sure it's probably Konami but in six years we could easily see Sony owning the MG franchise and suddenly this split means nothing, like when Interplay went down and PC fans thought Fallout was dead. Ring a bell?

If you want to make it fair create a thread called "biggest wii u sales success of the year". 

Rocket league sold a lot more and it went viral thanks to a genius move by Sony.  Putting it on ps plus.  Most of the sales came on ps4 and many of them since the first month.  The ratings have more than double on the store since then.
