you're 18? and your this reasonable? i somehow cant believe it

I'm not forcing you to believe it, but it's true.

You believe whatever makes you happy

Nintendo is not young gamers, it's casual gamers. Young, old, in between, anyone who enjoys Wii Sports more than Call of Duty. Unfortunately for Nintendo, these people generally do not purchase as many games, they usually only buy a few fitness, party, or kids games. This is especially troublesome now that Nintendo is selling both the 3DS and the Wii U at a loss, meaning they get even less profit than they did from the DS/Wii. This is also why Nintendo is trying so hard to cater to hardcore gamers while also trying to keep the casuals. It's a delicate balance.

no... NO!

you're married, atleast have two kids and you are in your 30's. end of story! if you deny that i will report you!

Well...that's your opinion. I'm pretty confident it's wrong, though. 

I´m 36, my brother is 47. We always attend Nintendo 3Ds meetings in our city and most of the people participating on it are on the range of 20-30 years old. Teens and kids are always about 25-30 % on those meetings.
So, yes, there´s a HUGE misconception about Nintendo consumers, specially from a big number or websites and magazines editors that think they know something about this huge videogame market. Many Nintendo consumers are, actually, older people who grew up playing on Nintendo consoles, and older casual players.
And there is always that old talk that Nintendo don´t make games for mature audiences... what is just bullshit. The real mature gamer is the one who has open minds to experience any kind of gameplay, to experiment new games with different approaches and creative works, and NOT those teenagers who scream for games with adult content just to inflate their mediocre egos.

Im 35 and my first Nintendo console was GameCube believe it or not. I always followed Sega until their demise, and turned to Nintendo as my next platform of choice. I had played on NES,SNES and N64 at friends or relatives though.
I think people label Nintendo casual and kiddy due to the Wii generation, but thats not always been the case. I also find COD to be the most casual game on the market.

I'm an old fart and I love Nintendo. I need a white cane and seeing eye dog to get to Gamestop and my eight year old nephew plays the games for me because I can't see them but the sound of Charles Martinet's voice makes my heart leap right out of my shirt. Thankfully, I don't have any heart problems.

I think the 'Nintendo makes games for kids' comes mostly from teenagers who own a 360/PS3 and older generations who don't really have a clue what's going on in the industry.

You mean the casuals, right ? There are a lot of people who grew up playing on Ataris and Mangavox and most of those guys know very well what the market is about.
