You know, I'm not even sure if you are serious right now.

I see there is a lot of white-knighting going on without me.

Not all people on this site would know all the varieties of games Nintendo does.if they weren't interested I don't think they will go out of their way to know all the franchises they can't play without a Nintendo system.You yourself on the op can't distinguish Activision EA and Ubisoft yet they all have a wide variety of games that could be said to be just as far as your example for Nintendo. Why hold other uses to a standard about one gaming company when you can't meet them for the biggest 3 3rd party publishers and developers

It's the impression stuck in many peoples heads it's all the same. Couldn't count the times friends go "meh" when I mention a Nintendo console and its games as fun things. Weirdly these consoles are the most played on friend weekends and deliver the most "fun".

Usually they adapt their opinion during play sessions but these opinion shifts don't seem to stick for long and next year it's SSDD at the "meh" reactions.

For all the things Nintendo tries and changes in new iterations in franchises they get the least credit while CoDs, FIFA's etc go like hot cakes.

Which would be an equallly silly thing to do ;)

I realise the point you're making here, but I wouldn't say Pikmin had any amount of story depth.

Quite funny that people accept to say "Nintendo games" when affering quality, polish, gameplay, focus, etc but don't accept the generalization for other things.

You are just overcomplicating your analysis. People say "WiiU is good if you like Nintendo games" just because you will have basically games done by Nintendo and almost no 3rd party in comparison to ps4/x1. Like someone could say buy ps4/x1 if you don't mind missing Nintendo.
sales on the platform prove it, games not made by Nintendo sell quite low, if not published by them you have an even worse situation. Could it be more simple?

Also all company have some kind of police or mentality. So not liking some company games can be a reflection of what that company do not meeting your desires.

I'm still not seeing how that supports your point of view. "Even an Xbox fan" can tell the difference between a 3D game and a 2D game, and they are also more than qualified to decided if they don't care for the mechanics, themes, and values that a 3D game and a 2D game share. I don't see how being poorly informed had anything to do with it. I can agree that 2D Mario and 3D Mario have differences, but im sure you would agree there are many things common to both. If a person does not care for many of those concepts then its certainly fair for them to say they don't like all Mario games. 2D and 3D alike.

New Super Mario and Fire Emblem do have something very important in common. Both games were allowed approval to leave the conceptual, preproduction, and development stages to be published to market. They all passed the same Nintendo "Stress test" as it were. If you don't agree with the values they use to make that decision, then there is a good chance you aren't going to like either game the same way you might not like either of the last two songs the DJ played. The DJ had nothing to do with these song's creation, buts its his decerning taste that determines if a song reaches your ears or not.  

So, a person who does not value the DJ as a connoisseur of music, is not unlike some one who does not value Nintendo as a connoisseur of games. Which is not unlike some one choosing to not listen to Glen Beck or Rush Limbaugh because they do not veiw them as a connoisseur or expert on politics. Are there not some people who might listen to some of the DJ's selections? or like some Nintendo games? or learn toward Beck on some opinions? Sure, but that doesn't mean that those who simply refuse to aknowlege them as an authority on the matter are being silly or unreasonable, they are just being descerning 

i was a segaboy till they died.  we had a cold console war in the family, my brother was nintendofan... wasnt easy after the DC...

Alright then, let me just pick apart your post. I don't think you have listened to any of the Nintendo music. The SNES always looked better than the Genesis, and the soundchip was ahead of its time.
