What does any of this mean? This is the core question presented by this thread.

Even if you narrow it all the way down to Nintendo EAD, you are looking at 3D Mario, 2D Mario, Mario Kart, Zelda, Animal Crossing, Splatoon, Captain Toad, Pikmin, Wii Fit, Wii Sports, Nintendogs, and more. That's a huge variety of titles developed by just a handful of studios.

Underlined you are so close to understanding. Bolded you keep doing it again.

Captain Toad is "like a platformer" inasmuch as it requires you to have an awareness of your position in a 3D environment. There isn't any actual platforming in it. Pushmo has some actual platforming, but it's such basic and straightforward platforming that I would be only hesitantly call the game a puzzle/platformer if pressed. Captain Toad I would not call a puzzle/platformer.

You know, I don't think you've actually played Wii Party or Game & Wario, and that's why you refuse to commit to a genre for them. VGChartz has a "misc" genre, so how about we settle on that?

A lot of people do that. "I hate Pixar movies" "I love Disney movies" etc. Nintendo games do have a certain style. You can almost always tell if a game is made by Nintendo.

Just like people saying "I don't like indie games". It doesn't really mean anything, as indie games can be anything (Yes, I'm looking at you, KaPi)

You are missing action games (Bayo, W101, Hyrule Warriors) and puzzle games (Pushmo, Toad).

And if you really want to talk about "what can be found on Wii U", it does have a handful of third-party games from last year and launch. ZombiU (and the recently-released-in-Japan Fatal Fram V) are survival horror. Mass Effect, COD, Need for Speed, Arkham City/Origins can all be played on Wii U as well.

You are also grouping 2D and 3D platformers together, which is pretty foolish.

I don't get your comparison with random house. To read a book you just need the book. To play Nintendo games you need a Nintendo system not just the game video game publishers don't have anywhere near the universal accessibility publishers in other media have. The best games on Nintendo systems both in quality and in sales come from Nintendo. The best on Xbox and PlayStation aren't as concentrated with their respective first party games. So saying if the like Nintendo games is also implying the library.

Pixar is not a producer. Pixar films are produced by Disney.

Saying you like or dislike Disney movies is just as nonsensical as saying you like or dislike Nintendo games. But there is a greater awareness of what movies are actually made by Disney's animation studios (and thereby considered a part of Disney animated canon) than there is of what games are made by Nintendo EAD.

I would accept "I (dis)like games made by Nintendo EAD," I suppose. It might still bother me that Nintendo EAD is actually about seven different studios, maybe even more. But those games probably wouldn't even comprise half of the Wii U's library, so I don't see why you would base your purchase of it on that. And a lot of people tend to group whichever games they see fit under the "Nintendo game" qualifier, leading to lists counting Tropical Freeze and Smash Bros as Nintendo games, but not Xenoblade or Bayonetta.

I'll help you out a bit:

The term "Nintendo games" is used because Nintendo heavily rely on the same franchises that have existed for the past decades. Mario, Zelda, Donkey Kong, Star Fox, Mario Kart, SSB (I'm only talking about homeconsoles here, if you include HH, then also Pokemon, FE etc.). Because, let's face it, a large part of Nintendo's consoles library have been heavily relying on the same franchises for a long time. Thus it sort of makes sense to say "Nintendo Games" because they mostly only develop titles in existing, heavily established Nintendo franchises.

My five cents anyways.

But if you say "I don't like Nintendo games," that has nothing to do with the games being restricted to a certain platform. It is collecting a vastly different (and downright unrelated) group of experiences into a single category with no clear definition other than having a shared publisher.

I changed the underline to italics. Wierd.

As for your bolded statement here, you are incorrect. Most of the Nintendo fanbase likes some of their games and dislikes others. I'm a huge Zelda, Pikmin, and 3D Mario fan, but I don't really play much 2D Mario and I've never tried Animal Crossing. It just doesn't look like my kind of game -- for a variety of reasons, none of which are arbitrarily determined by who published it.

You are saying there aren't enough differences between Nintendogs and Twilight Princess to "try and class them separately." You can't see how nonsensical that is?

They mean kiddy colorful lacking complex story characters and emotions type of games while mostly centered on just gameplay. Exceptions to the rule like a 1 zelda per gen. But the general stereotype is kiddy colors lacking maturity. That's Nintedno to most, even Miyamoto said he cares about game play not stories.
