Once again, Moogle, the one who is always swayed by the press.
Killer 7 was awesome.
And you aren't getting the point of adult games, they aren't supposed to be pornagraphic or even M-rated, adult games are things like God Of War, The Godfather, The Suffering, Metal Gear Solid, Max Payne, Mafia, Eternal Darkness, Resident Evil, and Silent Hill if you want to use the M-rated example.
They aren't meant to be excessive in blood and gore or etc. they're more involved and mature. For example, God of War does have lots of blood and gore, but do you really think a kid is going to take it the same way? If you tell a 13 year old to play it, he'll have a much different time than a 24 year old, not because of the game's adult content, but because of the way the story is told. That's why Killer 7 is a good example, it requires a different type of person, an older person, to see it properly.
The Suffering mixes adult content WITH a adult story, it's very intricate and emotional, and it's not the same as, say, Kingdom Hearts, which has much lighter tones and doesn't delve as much into a character's pysche.
In The Suffering, you encounter LOTS of metaphorical references to Torque's (the main character) mental condition, his feelings about the death of his family, the notion that he could possibly have done it himself. It leaves you wondering what kind of character he truly is, where the second game shows that he's just as confused as the audience. Is he bad, or is he good?
And if you want to see examples of games that are good for adults, yet aren't mature rated, then why not look at Homeworld, Planescape Torment, Baldur's Gate, Civilization, or even the E-rated Legend of Zelda series. Their ratings do not create the game's audience.
So Moogle, if a game is M-rated, does that actually make it a mature game? No, not really, play Grand Theft Auto for example, I wouldn't call that mature, it's juvenille actually, and the same with things such as State Of Emergency and Postal.
Nintendo has PLENTY of adult games, you just can't really decipher what they are.
Oh, and Killer 7 didn't get bad ratings. Look here.

Gamespot hardly ever reviews a game with bad judgement, and consider the fact that there are millions of people on the site, I doubt the user ratings can be off either. Besides, look at the industry average, 7.7 is not "bad".
EDIT: You actually enjoyed the Castlevania games on the consoles? ABOMINATION!
