maybe a good idea

As usual, you get bitter about something do with Nintendo.

Never change.

^.^

I wouldn't mind a few more mature titles developed by Nintendo. If they do develop some great if not, it's no big deal. Just as long as they keep making timeless classics thats all I want from Nintendo.

Nintendeo owned 49% of Rare which was a controlling share.  That made them first party, not 3rd party or, colloquially, 2nd party.

Nintendo doesn't fully own GAme Freak, who make the Pokemon games.  Would you then say that Pokemon is not first party?

Pokemon is technically a 2nd party game (Colloquially), but a 1st party IP.

Controlling share doesn't matter. What matters is full ownership, a.k.a. acquisition (as far as the definition goes).

Wikipedia:

First-party developer

In the video game industry, a first-party developer is a developer that is part of a company that manufactures a video game console, and develops exclusively for it.

->  First-party developers may either use the name of the company itself (like Nintendo), have a specific division name (like Sony's Polyphony Digital), or have formerly been an independent studio before being acquired by the console manufacturer, such as Rare or Naughty Dog.^[1]

(happyD note: in this occurence the mention of Rare relating to its acquisition by Microsoft, not Nintendo, as that never happened)

Sorry to be pedantic, but sometimes Viper it's necessary.

I would love them to do that,I dont mean just realistic graphics but games wit more mature themes.I wouldn't mind Zelda doing that either as zelda games always have great storyline ideas but they dont really put much focus on them

The type of game to cater to more adult audiences didn't require a M rating, let's make that clear. Actually, they likely shouldn't require an M-rating in alot of the cases. My prime example was Uncharted, and it had a T rating.

Controlling share does matter.  Rare couldn't have developed a game for Sony or MS if they wanted to back then because Nintendo called the shots.  Are you suggesting that Game Freak, Project Sora, Nd Cube and Monolith Soft are 3rd party?

And don't fully rely on Wikipedia.  Especially when the data isn't sourced from anything. 

A 1st party studio that is wholly owned is referred to as an internal studio.  External first party studios would be those not fully owned but do have a controlling share...such as those I listed above.

Some "mature content" is more quality than others, but I think broadly that statement is correct. Ask any teacher/person who works with kids what games the ten year old kids are into at the moment and you will find the vast majority are into the violent/"mature" stuff for obvious reasons.

A guy who works in Gamestation told me that it is a battle to get the kids to try anything which isn't violent or "mature". These kids claim anything which doesn't have mature themes is "gay".  That's immaturity in a nutshell.

When I was a kid we would gasp in amazement at the pixellated blood in Mortal Kombat, some would even claim it was a better game than Street Fighter 2 because of the "more realistic" graphics. Only in hindsight can we now see this was a bit pathetic - the theme of the game is just the window dressing, it's all about how it plays.

In short, a gamer should be out to play quality, regardless of the theme. I'd say it would be inadvisable for Nintendo to stray to far from what they've been doing so well all these years. Stick to what you do best etc etc.
