The point of gamers wars?

So far since the announce of the most recent generation of consoles, Sony, Microsoft, Nintendo and PC users/gamers, are throwing barrage after barrage of thrash talk against the consoles that they are not planning to pick up, to some extent I understand this, what's the point? is beyond me, as most people go out of their way to make the other consoles look bad, fanboyism and trolling are obvious participants of this "discussions" but my real question is, what's the goal of all this? what's the purpose of this "system wars"? is it to make someone regret their choice? or is it a way to mock other people? or are we doing the PR and marketing job of global corporations and try to destroy the competition? are they to make someone else change their choice?

it's a sport like football. except for basement manvirgins like me

I'm on sony payroll

Who's gonna rule the world? Arms dealers. The rest is too busy fighting each other.

@drekula2: are there any regulations to this sport that I should know?

my dick is bigger than yours.

It's not about games or consoles.. it's the longest human debate that has ever been had and will never be resolved. In other words.. the "I'm right and you're wrong" argument.
