Hypothetical Situation.

[General Mostly Electrified Steel]

Let's assume you are you.

For the most part, this means that your personality is a specific and finite subset of your mind, which can be taken to be personality + unconscious.

However, this becomes important for the next bit.

You are everyone else.

Now, the question:

Who are you? There are no rules, and the framework is simply that: a framework. You can paint it, stretch membranes over it, play jungle gym with it, snap pieces off and beat people to death with it... the choice is yours.

But...

Who are you?

 

[The Reverend]

I am Legion.

 

[Selka]

an otter, I eat clams.

I am bizarrely reminded of <a href=http://www.youtube.com/watch?v=GBYQIYQioUI>this video.

I am large, I contain multitudes.

It's a question without an answer. If the question is what I would be if my consciousness were to suddenly be in control of everyone else's the answer would be that I am me. Nothing changes, except that I would eventually go quite batty. That answer, though, is based on my view that we are self-defined. If one views things in the opposite way, and instead argues that we are defined by interaction, the loss of all other consciousness would be a loss of self. Of course, if you're a solipsist, the world is entirely within your brain anyway, so everything is a creation of your imagination

I quite agree, I must say that i am me, for that is all i know that exists, "i think therefore i am" etc. As for what I am i must be a thinking thing. But as per a physical existence I cannot say. Does physicality even exist, it cannot be proven, thus I can imagine myself as anything I wish although I cannot ever prove that that extended part of myself exists. As for others, are there even "others"? perhaps there is only me, as i cannot prove that any "other" exists. It can be said however that all these things i have an idea of exist as ideas, as modes of my thought. But now i'm getting off topic.
To get to the point, my only logical reply to this question is, "I am me, and I am a thinking thing."

[Rannath]

I am buddha, I have acheived true nirvana.
OR
I am Legend, who is not a black american, but an old white british dude, seriously, If you can't keep the nationality right you can at least keep the age right and cast Morgan Freeman.

 

[MagnetoHydroDynamics]

I am the result you get when you divide by zero
I am the inversed thermodynamics
I am the perpetum mobile
I am the last cipher of PI
I am two places at once, superpositionous
I am reflecting everything, but I appear black
I am the end of the universe
I am the 101%
I am THE UNREAL

Other than that I am Tchalaác, a 2.5 meters tall red mutant with steel for bones and teeth and kevlar for skin, an inpenetrable armor, arcane mage skills and a 10 ft. spear.

 

[000Ronald]

I am me

and I am you

and I am you

and I am you

and I am you

and I am-

(hits self on the back of the head)

Enough already, they get the f***ing point!

 

[Moroha]

Me!

 

[Anarchemitis]

I think therefore I am.

Video Games can be awesome.
Star Wars Battlefront is a video game.
Therefore, Battlefront may be awesome.

It is raining.
It is not raining.
Therefore, my glass of water is made of pomegranates.

Seriously, what is the specific point of this post? You could say in much simpler terms
"If you are playing a god game, or playing a shooter, what do you think you are as an existence playing it, other than a human being?"
