Crazy to think ZombiU wasn´t profitable, almost 1 million units sold.

If I'm honest, I'd rather have a bunch of old IPs of exceptional quality than a bunch of overhyped poor quality new IPs that PS4 and XB1 is littered with. By my estimations PS4 and XB1 don't have a single great game that isn't a remaster of a last gen game. Not a single one. That's an embarrassment to the gaming industry after this much time. 2014 was a disgraceful year in gaming for all but Nintendo, and that's not a biased statement, that's objective fact.

Animal Crossing, Brain Age, Nintendogs, Golden Sun, Pikmin, Xenoblade Chronicles, Chibi Robo, Endless Ocean, Excite , Steel Diver, Fossil Fighter, Batallion Wars, Advance Wars, and Sin and Punishment are some of Nintendo's new IP's in since the release of the N64 which had sequels. Of course Microsoft and Sony games will mostly be new IPs because they don't have the old ones to work on (since 1995 - 20 years ago.) I made sure I didn't add any game with main characters from another video game series and games that were only one release/the IP remained in possesion of the developer(I.e Rare games like Banjo Kazooie.)

As far as brand new IP's unrelated to previous Nintendo brands, this topic is a fact. Let's face it. Nintendo fans buy Nintendo games, and unfortunately, new IP's after the N64 era have been included in that group. It's why Nintendo puts the most emphasis on their "Big 10" and why third party studios and publishers care very little to have anything to do with them. It's unfair to blame Nintendo for such problems; it's the fans.

ZombiU VS WatchDogs
from other thread

Watch Dogs is a GTA clone,  Destiny is a Halo "spin-off", Titanfall is a COD with robots wanabee, Driveclub is an upgraded Motorstorm and The Evil Within is Resident Evil bastard child.

New IP/name =/= new original game!

Funny how Nintendo always breaking the mold with its series is "rehashing" & others always making the same game but with new name, prettier graphics & modest changes are "making new software".

I find it appaling when people won't go beyond the envelope & fall for cheap marketing tricks!

Shovel Knight.

The devs basically starved themselves while developing the game largely as a Nintendo exclusive. It's a huge financial and critical success -- enough to now come to PS.

Like others have been saying, you're kind of making strange parameters for this thread.  You talk about the Wii U not having any successful new IPs, and put strange restrictions on what is considered a "new IP," yet you put games like Watch_Dogs (which the Wii U did actually get), Transistor, and Destiny on the list for XB1 and PS4, which are multiplats.  Also, given the titles you listed, these naturally favor XB1 and PS4 due to them having much stronger 3rd party support.  

Oh, and not only that, but Project Cars is also going to be on the Wii U.

But this thread is really strange to make in general, because it's not that surprising at all that the Wii U hasn't had a very good time with new IPs.  The system itself hasn't even sold enough units for it to be easy to do.  The biggest chance the Wii U has is for Nintendo to release the new IP, which is unfair to compare to the XB1 and PS4 when you look at it like that.

I think both Captain Toad, Hyrule Warriors and Nintendo Land can be considered new IPs - and successful ones at that.

Captain Toad became it's own thing even if it was based on Mario 3D World's bonus stages.
Hyrule Warriors might share game design with the Warriors series, but it's also it's own thing: characters, enemies, items. It just plays like a Warriors game.
Nintendo Land might be a mini game collection based on Nintendo characters, but other than that, those same characters are used in different types of games, with only a few being to already existing games.
