I'm going to say the same thing to you as I have him go and read the post he replied to before replying yourself and you'll see I've already addressed those games to begin with, W101 is also a first party game aswell as being niche (ironically it outsold both COD and AC and is at around 400k) and LCS and ZombiU sold well hitting the 1m mark with LCS also being funded by Nintendo themselves, Rayman Legends is the third best selling version with only the PS4 and PS3 version selling more out of all 7 versions released. Essentially you just backed my stance as legitimate efforts did well.

ZombiU's port to PS4 and X1 was barely even a blip as it was handled in the same way third parties handle their efforts on Nintendo platforms and guess what it bombed hard showing that no matter the userbase if you half ass it you won't get good results.

Not true.  There are huge incentives to have a launch title available.  Think about it.  Ps4 might have 40+ million units, but how large is the library of games?  In the hundreds, thousands if you include the indies.  All those titles are competing with each other for a piece of that market.  At launch, NX will sell a few million units with a library around 20-30 games.  Lack of choices means even crappy games could sell a good number.  The smaller library means more exposure for their titles.

Those games didn't bomb, just didn't do as well as they could because ubi and activision didn't try. You know, those who own the games are the ones who need to try.

W101 isn't third party, need for speed was 6 months late, deus ex was late and released for $50 on wii u at the same time it was rereleased on ps360 for $30. The other games you listed sold very well.

edit: looks like someone else already said just that. Still valid.

Ubisoft and Activision lost millions of dollars as a result of these ports. Why would they bother even putting in the effort of making these games and losing millions if they didn't legitimately think they had a shot of at least breaking even? Do you think these companies enjoy throwing away millions of dollars? Not try? How about they decided that it was better to not spend good money over bad. I highly doubt a bigger, much more expensive push in marketing, features, price point etc. would have led to sales that would have gotten that added money back.

Source? None? I thought so.

Wonderful 101 is first party, but it was worked on by a third party company. Third party support is not limited to third party ip. The fact that platinum put a lot of work into wonderful 101 only for it to bomb is idiotic. Almost anything platinum makes is niche, so you can't say that it failed because it was niche. Likewise, the game had virtually no marketing. How are other third party devs supposed to collaborate with Nintendo if Nintendo doesn't put their part in as a publisher to market the game.

Lego city didn't sell that well despite reaching a million (reason for the 3ds port), and zombiu was confirmed to have bombed (just because zombi bombed everywhere else doesn't mean zombi u did well). Those two games were designed as exclusives and performed poorly to the point of needing ports to recover costs.

Rayman legends is the game that hurts your case the most.

Rayman was publicly said by ubisoft to have performed poorly, regardless of how it did compared to everything else. 

Rayman was the ultimate third party game for Nintendo - age appropriate, designed as an exclusive, utilizes the gamepad, known IP, devoid of bugs. The fact that this game lost to the ps4 port (no tablet support, different audience, lower install base) is utterly laughable. This game should have dominated on the wii u, and it didn't. What the excuse now?

likewise, you didn't addres need for speed or deus ex. Both well made ports that ... Surprise surprise ... Bombed.

Nintendo should have put in way more effort to have made these games successes. What third party company would want to work with a platform where well made games are sent to die?

Third party support is not limited to third party ip.

a port coming late should not be an excuse for poor sales. Next gen versions of GTA, last of us, and Destiny sold very well on next gen despite being "late"

The other games listed did not sell well. Rayman and zombiu sold poorly (source: Ubisoft). That was the whole reason for the ports to other consoles.

That's not true at all, the 3DS version isn't a port, it's a completely separate game that was in development concurrently with the Wii U version. 

DLC? so what? the vanilla game is still good. PS3 and PC got DLC later and that didnt stop those versions from doing well and not everybody buys DLC anyway, lot of people dont. AC3 being good or not is subjective again didnt stop it from doing well on other platforms and what of AC4 the onei most people did like, whats the excuse there. No Bayo 2 is a niche Japanese games thats not trying, Fallout, GTA, hell Destiny had Ninty gone for those THAT would be trying. Its good that they saved it thats great, but how well did that do in the end?

Its nobody's problem, but Ninty its there systems that are missing the games.  Why should Nintendo try? because they havent before and no i didnt say vouch for wayward 3rd party games, stop putting words in my mouth. Im saying if they go to these guys and WORK with them to ensure that the ports are up to the others or even trying to get some popular games on there system then it would help all involve you know, the way Sony did it when PS3 was getting stomped they actively went to 3rd parties to help get the games to be not as crappy as they initial were. Cause what they are doing now...aitn working and you better hope people like Ninty games as much as you do so they will buy more of the system, but considering the current trend im not holding my breath.
