Automatically uncreative no. There are some mature games that are creative. However there are a great many that just mail it in because they can go over the top with gore. I like plenty of violent games. But plenty of them are crap. I feel much more hesitant buying a mature game without playing it first instore, demo or getting friends opinions because of it.

A mature game isn't any better then a game without extreme violence or any worse. The Gameplay is what will decide that. I also don't see the Wii not getting mature games either, so i don't know where that's coming from. Nintendo isn't making any super gorey games... but why would they? Having Nintendo creators make the next Manhunt would be like having the Manhunt creators make the next Mario Brothers game.

Mario games wouldn't be any better if when mario jumped on a turtle his guts would pop out is my general point.

Joke post?

If you call the 50th mario creative for adding a few new gameplay elements and the 2nd killzone generic for adding a few new gameplay elements then you are either a liar or a fanboy.

How often is it that sequels are creative in any game? Almost never. That's why it's called a sequel.

 Nintendo sequals are often inventive and fresh (there are exceptions like Mario party), but SMB games are rarely the same

lol oh god, Samurai Warriors on the Wii? I took a quick look at the couple of seconds of footage on IGN. . . Others may have their opinions, but I'm going to steer clear of that game.

It looks just like all the Samraui Warriors/Dynasty Warriors games except first person as far as I can tell.  Of course that's the big problem with it.  It doesn't look any better graphically then a PS2 game.  For me it's more about the history, but the gameplay looks fine to me, assuming that it works more like a Samurai Warriors games unlike the gameplay demo where everyone dies in one hit. 

I think the video looks worse as well just because there is no sound.  Those games tend to have some really good soundtracks.

I disagree about the soundtracks, but that's just a preference. History it may have, but I just find that the games get repetitive and I'm tired of playing the same thing again and again in those games. I haven't played the Samurai Warriors games, but I've played multiple Dynasty Warriors ones. I like hack'n slash stuff (though it will get repetitive after a couple of characters), but that series seems kind of similar to Madden.

It may be in first person, but I'm not finding that much of a reason to be excited for it, but obviously that's just my opinion.

I don't understand why this thread exists...

Miyamoto is one of the best developers out there...whether you're a Sony fanboy or not, it's not your place to say "Miyamoto needs to make violent Mature rated videogames." He does what he does best...and that is make awesome platformers, arcade sports titles, whatever...almost all the games he makes are truly fun, and that's why they sell millions upon tens of millions.

I'll go ahead and respond to the original post. Yes, Miyamoto's / Nintendo's philosophy is to blame for the small number of M-rated titles on their previous consoles. But there is no lack of "mature" titles for their previous consoles, as people who are actually mature can explain to you.

Exactly! I completely agree with almost everything you wrote here. A game having adult appeal has nothing to do with it's rating. A game rated E and a game rated M both have equal opportunities to show mature themes. Saying all E rated games are mature is stupid (go play Hannah Montana and come back and say that), but conversely, to claim all M rated games are mature (in the classical sense of the word, rather than the ESRB rating) is just as stupid.

Examples of Mature, and violent games:

Killer 7; had a lot of creativity and some mature political themes. It was not a game for kids, despite being gorey. Most teens would have gotten bored with it (or not understand it).

Bioshock; is another perfect example of a violent but mature game. It has dark themes of morality that are far above what the standard teenager looking for mindless killing will be able to tolerate.

Metroid Prime; this isn't a game for the simple minded. The puzzles and themes are again, far too complex for some teen looking for a simple violent shooter.

However, a game that has an E rating can appeal to adults too. For example: Wii Sports, Viva Pinata, and Mario. These are games that anyone can play, and that's what Miyamoto appreciates. He wants games that appeal to adults and children, not one or the other exclussively, and I believe in this respect he has been largely successful. If anyone really thinks Mario Galaxy is just a kids game, I pity them.
