Me? Guybrush Threepwood.

Who else can use a rubber-chicken-with-a-pully-in-the-middle and can't die?
Not to mention all the cool pirate stuff that goes on in those games

Kratos of course, he is the Chuck Norris of Video game.

Adult Link in OOT. Chicks dig tights, and I'd be shacking up in the hayloft with Malon at her ranch on the regular. Save Hyrule? Ok, maybe in 40 minutes, kay?

Of course the swordfighting and archery would be fun too, but I already do that in RL. =) Shacking up with hot elven farmgirls, not so often. ;)

Zeratul, leader of the Dark Templar from Starcraft. I could strike from the shadows with a cool souding sword and I'd have that awesome deep voice too.

And if I were to choose a vilain I'd choose Kerrigan. Being the queen bitch of the universe sounds really fun!

Pffff, you are all thinking WAY too low. This is the correct answer:

But in reality I think Link.  Double clawshots, Master sword, cool fantasy setting, Zelda, Malon, The hot Gerudo leader, hell even that creepy stalking Zora chick from OOT.  First order of business: choak tingle to death with the bloated corpse of Navi.

I'd be the guy in Doom.
