Why? Those hardcore gamers doesn't have something else with more explosions and decapitations to play?

Are they closeted Mario fans? Or is this some sort of guilty pleasure they have?

Definitely Nintendo. People on VGC often complain about Nintendo for its lack of hardcore games, its lack of third party support, and the fact that it always feels like it's a generation behind its competitors.

There is this never ending power struggle between Sony vs Nintendo + MS. The MS and Nintendo camps take turns taking stabs at Sony for various reasons. Sony camp is usually in "defense force" mode to combat the nonsense. I have sensed for some time now that Sony is a victim of Nonconformist Conformatism. People love seeing a giant fall. Basically, Sony was an indisputable lead for 2 generations in a row, far more than Wii and any other main console. Not to mention the general bad blood due to HOW Sony first got into the business in the first place. MS also has always specifically had an out for Sony Playstation due to their fear it would replace the PC. A lot of this has emulated in the fanbases.
Sony is the Obama of gaming; every failure capitalized on but every accomplishment ignored. 360 fans often undermine any of the great PS3 exclusives because to admit that it has so many means to recognize they might not have backed a "winning" horse from jumping in so early(not sales wise). Nintendo fans are relishing in their victory finally after 2 straight losses and the fact Sony is on the bottom is icing on the cake after every game they ever loved was taken by PS1. There is a general consensus that Sony and it's fans alike are very arrogant(probably true) and everyone just wants to take them down a peg (media and opposing fans )....regardless if they are right or not about what a great products they have ;). Sony does do it's own share of just leaving themselves wide open for ridicule with some of their very poor choices.

I'm going to have to say they're all about equal, Sony gets hammered on for being poor, Nintendo gets hammered on for being kiddy and underpowered, Microsoft gets hammered on for not enough first party titles.

Hating is just another form of admiration. And as it is, vgchartz is wayyy tsundere for Sony.

Well, it seems that I'm not hardcore so obviously I don't know what they like in a videogame. But given the amount of hate Nintendo games get for being kiddie from those that call themselves hardcore, I suspected that hardcore gamers would prefer games with violence, girls, or foul languge.

But anyway, why those hardcore gamers that criticize Nintendo then play Mario games hidden in their basement, like a 14 year old who is hiding from his mother when he's masturbating?

In general: Nintendo
On VGChartz: Microsoft

OK, that made me smile.

"I hate you Sony, and didn't want to play your games, anyway.  Hmph!"

I think the majority of fans are Sony, followed by Nintendo then Microsoft.  Nearly every poll on this site reflects this.

The first sentence is a statement (using a certain definition of hardcore), and the last one is a question.

I was using the term hardcore to describe those called "adult" in this post of your "Evidence That Nintendo is Not Serious About the Hardcore". I guess this is what happens when everyone uses his own definition of hardcore.

I would find shocking to see those grown men playing Nintendo games on their PC.
