Well, that was a shit game. The controls were slippery as hell, but on to the philosophical shit.
The most important question to ask is "Who does the voice represent to you?"
My answer? Nobody. It was some arrogant jackass I don't know, meaning that I had no reason to listen to him (In my mind, I repeated the text in a my own voice, so, as what was being said went against what I was thinking, it was no one's voice) and he was giving me no reason to listen to him and, considering he was being an ass, I didn't. I did listen a few times, when he was telling me to do things that were beneficial to me, so I didn't rebel for no reason, nor did I obey for no reason, I did what would benefit me.
Also, some things that interested me:
I didn't give any bit of a damn when I said I am male and he called me a girl, yet I did when the opposite happened on my second run. yay, more evidence that I'm transgender. goody.
When he said we would meet soon and asked what my reaction to that was, I said I was excited. Mostly because I wanted to see the guy I wanted to punch. I was kind of disappointed when the ending was just me walking away.
I'm a rather submissive person. lulz.
Now then, is this art? Well, that depends on what your definition of "art" is. Mine is fairly simple. "Explain or discuss some element of the human condition." So yeah, I'd consider this art. For further example, here's some games that I think go beyond entertainment and are art:
Deus Ex: Human Revolution. (I've never thought about transhumanism and after playing this thing, suddenly I have an actual opinion on it)
Medal of Honor (Singleplayer only. It is painfully obvious that the devs really went out of their way to try and figure out the mind of a soldier)
Assassin's Creed Series (Mostly about ends justifying the means. PS, Brotherhood less-so then the other two, I think that Revelations is going to pick up the philosophy stuff again)
