I don't dislike Nintendo, since it was the company that got me into gaming with Super Mario Bros. 3 and Super Mario World. I love those games to death. I don't mean any offense by this, but it's the fanbase. They love the games, sure, and I have nothing against that. But when they state The Legend of Zelda: Ocarina of Time is the best game ever created in the history of humankind and no other game will ever come close to it, it just feels like taunting. Maybe subjectively, but there are many games out there that will give it a run for its money. I feel like they say it to annoy the hell out fans of other games, dismissing their liking of their games to say Zelda or Smash are the best thing since sliced bread and nothing will surpass it. Maybe this point of view is skewed, but that's how I see it. Honestly, I personally don't like Zelda or Smash; never seen the appeal to it. Additionally, I don't feel like Nintendo's recent entries feels as fun or quirky as their older games. I'm not saying the Wii or the Wii U are for kids. It's that the games aren't appealing to me.
If you'd ask me 10 years ago why do I hate Microsoft, I'd probably blabber a nonsense rage. Back at high school, I had to face some Xbox fans who would say Halo and their console were the best thing ever. And then I heard about Aaron Greenberg and I hated the console even more. His childish, immature attitude against the competition detracted me from the console even more. Back when the console came out on 2001, I didn't hate it or anything. Whenever I saw a Xbox commercial on TV or ads on the magazines, I just thought "Hmm, nice." and flipped the page. I just think the loudmouth fans messed up its image for me, and I didn't want to be associated to them by buying the console. Then Phil Spencer arrived, and my perspective on Xbox softened up a bit. He might look arrogant, but he's much more respectful and down-to-earth than others. A good mix of everything. I still wouldn't buy an Xbox One, but I respect the guy.
I have a PC (well, a laptop). I use it for web browsing and homework. I also use it to play some old games that can be played with non-intensive hardware. I don't have a gaming rig that can play Crysis in 4K and 120fps. I prefer a controller rather than mouse and keyboard. I just don't appreciate PC fans smothering in everyone's face how they are the "master race" because they can play with near-realistic graphics and seamless framerate, unlike the "peasants", who have to play on a console that's outdated when it releases. I won't be technical here, but that deplorable attitude is why I stay with console gaming.
