People are still arguing over this?
That contest was a popularity contest pure and simple, nothing more, nothing less. It shouldn't have been named "Which is the greatest video game hero", it should have been "Which is your favorite video game hero".
Reading some of the comments earlier on gamespot, bashing each other over the heroes backstory and such was pretty pathetic, and the hypocrisy of some of the stuff was somewhat hilarious. Like for example when mario fans were bashing Gordon for having no personality. Or the Link fans bashing Gordon for not talking.
As someone on the Gamespot forums said. "If this was about which one that is most powerful or has the deepest backstory, The Nameless One should probably have won by default. But he went out in the first round."
And yes, I voted Gordon, and while he might have beaten Link without that Steam message (They did not promise any discounts on it, it was a cool surprise when I saw that, even though I own all the HL games), I think he would have had troubles beating Mario.
It also surprised me how so many people over there had never heard about Freeman before. I saw quite a few people saying that they should test out the HL games, since seeing as he has such a huge following the games had to be pretty good at least. These people seemed to be some of the most reasonable people there, and I tip my hat off to them.
