The Wii.  You can play Super Monkey Ball Banana Blitz (which is one of the hardest I've ever played) with one hand while eating Cheetos with the other.  It doesn't get any more hardcore than that.

depends on your personal taste, personally I would say Wii, I;m a hardcore gamer and I find that what the Wii offers suits me play-needs

What does it matter? In the end, hardcore is just a vague definition thrown around to satisfy some modern gaming Status Quo that for some reason tries to define itself as being a more "mature" or "L33T" gamer than the rest. 

A gamer is a gamer, no matter what. A gamer plays whatever game he likes or that he finds entertaining. A gamer does not shy away from a game just because it's presentation isn't all real-life like or insanely over the top. A gamer can take a step back and enjoy games for what are, and give proper credit to all games that deserve it. 

I for one, am a gamer that likes to play on every console and PC, equally. At this moment, i'm pretty much only playing DS and PC (DOTA and DA:Awakening). Does that make the DS a more hardcore console than the rest? Nope, because I love it, as just as I love the PS3, the Wii, the 360, the PC and the PSP. 

In the end, that's what really matters. That each console gives you a satisfiable experience.

It's the PS3 or the 360... depends on your tastes. Huge "hardcore" libraries and excellent exclusives on both, and the online services kill the Wii's terrible online system.

Myself, I'm going with the PS3, mainly because I love Sony's 1st party to death.

Just because there's no blood and gore,

it doesnt mean its not hardcore.

Remember that.

I pick PC.

I pick the Wii because, you know, stuff....

Mmmmmh snobcore maybe !

My father is an hardcore minesweeper player.
