Nintendo was never considered cool. Hate to break it to you but even Sega was considered the cool system for teens back in the 90's even though it failed to beat Nintendo. Nintendo has always been the family friendly console. I'm sure many of you here have taken a marketing class and taken classes on target demographics. Nintendo has always chased children and families and no, the N64 was not aimed at adults. This is not an opinion. They learned how to focus on a specific target market with characters from Disney. They used to license cards for children before they even laid their hands on a  videogame console. You can like Nintendo as an adult, but thats because Nintendo is trying to appeal to the inner child of most families but are mostly focused on children. They want you to sit with your family and friends and enjoy a friendly game or sometimes even a single player game or two. They still to this day are focused on family couch gameplay.

P.S.

Nintendo doesnt make games for adults. The highest they go is Teen. They fund second party to make their mature rated games. This is what Rares job was. Nintendo themselves dont go beyond Everyone to a Teen rating for first party. Look at Bayonetta.....thats second party. They know they need a more mature image and need "cool" games so they are paying outsiders to do what they wont. Goldeneye was a second party Rare title made for Nintendo. If Nintendo was so sure they wanted to make mature titles with violence they would do it themselves, but that would tarnish their image which is essentially squeaky clean.

Rares games were more adult oriented, but Nintendos games were not. The clear difference between intention of first and second party, my friend.  If you ever got that feeling of mature gaming from Nintendo remember it was mostly Rares doing  as Rare carried the other half of their burden. So sad...now they are gone and their IP's belong to Microsoft now. I wonder how mature their titles have made Microsoft seem. Not much at all as it seems, because Microsoft always endorsed mature titles. Gears is first party now, which is something Nintendo would never do to tarnish their good name.

Elder Scrolls isnt coming to Nintendo consoles nor fallout because no Nintendo console has ever been up to par when they launched the titles on consoles. Nintendo is a non-entity because they don't play ball with the third party who push the limits. Nintendo though loved in the 90's was considered a joke to the PC realm and not even considered a threat at all. It wasnt until Sony that the PC realm became threatened, hence the Xbox.

I agree that Nintendo consoles have always been seriously underpowered, but even with the power to match the other consoles games like the Elder Scrolls and Fallout series won't come to Nintendo's consoles because of their strict and overbearing policies towards violence. 

Third party and second party can make mature games and RPG's for Nintendos consoles. There is no barrier outside what Nintendo creates for themselves. Mass Effect 3 was on the Wii U was it not?  Nintendo doesn't make mature titles themselves and thats the way they like it. The first party that Nintendo makes is what truly represents them, but they welcome third party as long as third party takes the back seat to their vison alone. Sony and MS get all the top third party titles because they work with third parties to make the consoles work well for both of their ideals.

As Bethesda said themselves on Bonus Round (on Gametrailers.com). Nintendo is to blame for the loss of certain games on their consoles because they did not take the time to prep the consoles according to not only what they had planned but what third parties had planned. Nintendo once again created an underpowered console and then asked third parties to make titles for it after, hence why you see the last gen games mainly surfacing on the console. Nintendo damned themselves.

bethesda games are made for the PC... they are so freaking buggy and ugly that u need tons of mods to make em run and look fine.

While there are exceptions like ME3 (which itself dosen't have nearly as much violence/gore as Fallout), the fact remains that Nintendo consoles in recent years have not been very fostering for mature-rated games. 

tbh ive seen more people state their reason for playing nintendo games because they are not mature games than mature gamers saying they dont play nintendo games because they are cartoony.

Its become unthinkable for many to accept that mature rated games can simply be better than cartoony games (im not saying all are), and instead go around making excuses about how people have limited their content to just mature games.

and this goes back to the previous point I made, more mature gamers play cartoony games than kids play mature games. mature gamers ARE playing a wider range of games than kids, so its just a non issue which you are blowing out of proportion.

If some people like sales2099 dont feel nintendo offer similar content to that found in other games and therefore he does play then whats the problem with that? Its nintendo's fault for making too many of the same type of games. They are the ones limiting their own appeal. Not everyone HAS to like cartoony games, and the reason isnt because they are cartoony, its often related with the satisfaction gained from the game. It doesnt take very long before jumping on an enemy to watch them disappear gets boring, eventually people seek games where there are better animations, more interactivity, and so on.

resident evil 4 was on gamecube and wii, so how does nintedno have strict policies on violence?
