Be way of small spoilers:

I think it's sad that, for one, people think games need to be M rated to be good and second, that they have to be new. Not to mention Nintendo is still coming out with M-rated exclusives. Saying that it's "sad" is fairly ignorant in my mind.

Ace Attorney was rated M O_o..?

im not a big M rating fan games are usually way to over the top but, when Conkers Bad Fur day came out on N64 I played the game to death. Luckily i still have the cartridge because that game is a shit ton of money now.

Topic was made for Nintendo fans to discuss M rated games they like.  If you'd like to contribute some that you've enjoyed, post about it.  If you haven't enjoyed any, kindly leave.  If you would like to talk about your personal feelings on Nintendo and their marketing, find a topic where that would be appropriate, or create one.

On topic...

Resident Evil 4

Eternal Darkness (although it doesn't hold up that well today in terms of gameplay)

Zombi U

Bayonetta 2

While the gameplay of Eternal Darkness has aged poorly (which isn't exactly atypical of that generation), it was still an incredible experience...

I only have Bayonetta and Bayonetta 2.

All other 16+ ones are on PC or are 3rd Party games for consoles.

Check the video I posted above

That looks more like a list of all M nintendo games.
