Never, why should I be embarrassed to play some of my most liked games? I can just as easily play a round of DOTA or Starcraft in front of my friends and then play Pokemon or Mario in front of them as well. 

Your whole assumption is that Nintendo games = kids games, which is far from the truth. Nintendo games are for every age and for every gamer. Or at least, every gamer that has the ability to see and comprehend anything beyond the limited current view of "OMGZ I IZ THE HARDCOREZ".

yea i never Tell people i own a SNES, only my Sega Genesis

No, not at all.   But I grew up playing games in the arcade when pretty much all games were like pac-man, frogger, Donkey-Kong, Q-Bert, Etc.  They were all cute characters so I have no pre-conception that cute characters are for kids.

Really I think that mentality come from the PS1/PS2 generation when it became fashionable for Sony and others to paint Nintendo as 'kiddie' and the Playstation as 'mature'.

Frankly I always found anyone who thought that they were more mature because they were playing a game where blood splattered about and more realistic looks was pretty immature.  It's still a video game. 

Certainly there are kiddie games, but Nintendo generally doesn't make games for kids, nor for adults, they make games for all ages to enjoy, including kids.   But typically teenagers are 'too cool' for that and want blood, guts, gore, violence, sex, etc. thinking it's more manly.  Hardly, but it's a stage most males go through, most outgrow it, especially when they have kids of their own, some don't.

I feel sorry for you that you must define your "coolness" with videogames.

I will be playing Nintendo games until I'm 80, I don't care what people think of me. I appreciate quality, and Nintendo, for my money, makes the best quality games.

Amen. You cannot outgrow "fun", and that's what Nintendo does best.

Only game Ive ever been ashamed of playing is DDR. As far as Ninty games, when I mention Im playing them to others(I seldom bring up videogames in social events as most of my friends dont game) most people are interested in them. Be it Mario or Pokemon if I say Im playing it most people will say; "Oh yeah that game looks pretty cool how is it?" or "I used to play that game are the new ones any good?" Nintendo games, as always are made for all ages.

I always thought it was only the grade school kids that felt bad if they werent playing Halo and CoD (or whatever "in" game) with their friends.

"E" is for EVERYONE. That includes 18-30 males.

nope! im not ashamed! nintendo games are great fun and easily justifiable! 

im ashamed i play WoW >.>

No.

What does bother me is when my friends on Cross Country talk about Call of Duty, and I have nothing to contribute. That's why I'm thinking of reviving my 360 and getting Black Ops this Christmas.....

Also, they make fun of the Wii. A lot. Irrationally. And they make fun of me for playing Nintendo.

But even then I'm not ashamed. I like what I like, and if they can't accept it, so be it.

no bcuz no true gamer cant diss mario

He' s the king of video games,the one who represents gaming

only kids who didnt  grew up with ninty games say they're for kids

I dont know whats ur age but trust me
