I think you can because i am one of these people. I have owned every nintendo home console since the super nintendo and buy every game that is worth playing on these nintendo systems ( anygame that i would rate 7/10 or more}. My favourite franchises by far are the legend of zelda, metroid, and 3d mario games. I'm in my thirties now but my excitement for these games has not diminished, i'm still like a kid at christmas whenever these games get announced let alone released. I even get hyped over remakes like Majora's mask 3d and the possibility of Twilight princess hd.

So i consider myself a pretty huge Nintendo fan but i also consider myself a gamer. By this i mean that i just like playing great games and you are missing out on some of the best games in the industry if you do not own a Playstation system and  to a slightly lesser degree an Xbox system (it has less exclusives). The xbox systems have the likes of gears of war, halo, forza and the biggest 3rd party games will always be on the system so for me it was an obvious purchase. 

Moving on to playstation 3 took a bit more time. I got a 360 first so therefore i didn't really didn't think i needed a ps3, plus no one i knew had a ps3 but most people i knew had a 360. whenever there was any disscussion online about which hd console was better i always sided with the 360 over the ps3. And i would come up with the usual opinions that everyone used (better online, better ports etc) even though i had never played the system before, the only true reason i sided with the 360 was because i had a 360 but i didn't have a ps3 so therefore the ps3 is worse. move  to 2012 and the ps3 was getting relatively cheap and all the top games were as well because they were getting old. So i decided to buy a ps3 and see if it was any good, three years later and i am still thoroughly enjoying my ps3 and have almost completed all of the 75 plus games i have bought for it. Now i think the ps3 is an essential purchase for any gamer out there, it has great exclusives, a far greater number japanese games so their is more variation within its game library and it also has a superior achievement method because you have a greater incentive to 100% a game (its called a platinum trophy). Overall i think the ps3 is just as good as the xb360 and maybe i even prefer it slightly.

So in short i really enjoy playing on other systems, i may not feel the hype like i do with my favourite nintendo games (which is not necessarily a bad thing because you are shielded from crushing dissapointment if the game is a letdown) but i still couldn't do without a non nintendo console because i would be missing out on so many amazing experiences.

If you limit yourself to one brand you are only limiting the scope of what can be seen in gaming. You can be delusional and tell yourself you HAVE to buy from Company A in order to show your devotion and support. But at the end of the day Company A doesn't give a single fuck about you, even if you're a huge fan. Try what Company B and C have and see what they have to offer as opposed to A. If you don't like it, stay loyal to A. If you found something you like from B or C, great!

I'll never understand the mental barrier people put in front of themselves that disallows them to enjoy other things outside the one console manufacturer. It only hinders their own potential enjoyment. In short, you can be a "true" fan of anything, even if you try other things.

What kind of stupid thread is this?

No, if you own anything but Nintendo you're a disgrace and don't even deserve to live.

Only a true Nintendo fan can have an opinion on this.

Well, I grew up with a PS1, and own a PS4.

Despite this, Nintendo is my favorite company.

I think there are different levels of fandom. for example maybe there is a gamer loyal to a brand that accumulates a moderate collection of games and are completely indifferent to the competition. Then there are the fanatics that accumulate bookshelves and cupboards full of games, have nothing but contempt and utter disgust for the competition and choose to spend their time finding youtube video's of the rival console, then proceeding to post nothing but pure hatred because other people had a different preference to them.

Sure you can. You can be a fan of something and still enjoy the other options. Heck, you can be a fan of all of them. You don't have to limit yourself to anything. Just try the things that interest you. I have been a big fan of Ninten since the beginning, but I still enjoy games from the other companies. I did it before and never batted an eye. Sometimes I hate Ninten for the stupid things they do.

In short, you can enjoy whatever you want. Who cares what others think, haha... x )

But you are still a disgrace to Nintendo and Nintendo fans. : P Also, dat Xbox jab... haha, jk...

yes. It's best to own all consoles. I am a huge nintendo fan but I also own a ps4, xbone, and pc that I built.

Yes you can, but honestly i dont know where people find time to own more than one system!!

Yes you can. Liking other stuff doesn't make you a betrayer. The same how you can love Star Wars and Star Trek. Or Nissan and Toyota.
