I actually entered this thread just to see if you had responded yet. :D Nice picture. Mass Effect 2 has much more detailed characters.

EDIT: Naa doesn't count. This one maybe :

He's the shit.

An amazing Character is one who is well developed, and has personality.
My personal Favorite is Kyle Hyde

your solid snake? OMGZ!!!

As a deeply developed character, that ends up chosing the right things despite his disillusion, and that's realistically far from superhero exaggerations, my choice is Garrett.
For his humorous exaggeration, my second choice is the Duke.

Squall and Snake!

A big bad ass beard or at least some awesome mustache. That being said I'm going with Master Chief. I dream he looks like Chuck Norris under the helmet.

I like a badass who has a passion for killing anyone that comes in his way who happened to be a god of war until someone betrayed him....need i say mroe

KRATOS

Gordon Freeman =)

It's hard to say. For some reason, Link is my favorite character. Even though he pretty much has no personality.

However, my second favorite character fits this thread better, which would be Yuri Lowell from Tales of Vesperia.
