I won't, and I'll be encouraging others not to buy it as well, and for one reason.
It is horribly and irredeemably misogynistic.
Just to clarify, I am a straight white male American whose political leanings can only be described in one word as "moderate."
I'm not big advocate of "political correctness," nor am I on board with what tons of people are calling "feminism" nowadays. I'm just an educated person who sees the depictions and treatment of women in this game for what they are.
And yes, I realize that the game is going for caricature. If this were purely a caricature of the over-the-top, 80's Schwarzenegger, "tough guy hero," I would so be on board with this game. I love a good satire.
The truth is that the people who are going to play this game and one of the first things they are going to see is a positive portrayal of an over-the-top violent male hero who lives a life of luxury and has a pair of schoolgirl twins (who look distinctly underage) pleasing him orally while he plays video games. Then they're going to see that it is only the "hot chicks" who get kidnapped. Then they're going to see that Duke cares nothing for the world, or even the women he's saving. He cares about kicking ass for no reason other than the fact it makes him look awesome. He cares about saving the girls for no reason other than that they can and will please him sexually.
The problem is that I'm betting a lot of people who see this aren't going to see caricature. They're not going to see the depictions of uber-masculinity and the over-sexualization of women and think, "Wow, that's some clever caricature. In reality, it's sad that gender roles push unhealthy expectations on both genders."
I'd bet that a lot of men who experience this game are going to have, on some psychological level, the idea floating around of "Man, wouldn't that be awesome? I wish my life was like this."
And this is yet another piece of media geared around the horrible idea that only the hottest chicks (particularly those who dress like sex objects) are worthy of time and attention. In this game, it is only the hottest women who dress like sex objects who are kidnapped and they are the only ones whom the hero cares to rescue. You could say, "Well, it's not Duke's fault that only the 'hot chicks' were kidnapped." True, but consider this: if a woman who did not hold any sex appeal for Duke was kidnapped, would Duke take the needed time and energy to rescue her? Of course not. He'd leave her to her fate. If that's not shallow misogyny I don't know what is.
The whole thing is demeaning. It's a testament to how unenlightened people are regarding the history of women's liberation and how portrayals of this kind are negatively affecting both genders.
Now, don't get me wrong. The developers have every right to make this game. And stores have every right to sell it. And consumers have every right to buy it. I'm not attacking any of those freedoms. I'm just saying that I hope the general population will see it for what it is and not buy it rather than buy it, praise it, and contribute to the stifling of social gender enlightenment.
I feel bad for Gearbox, as I know that saying "I hope this game fails" is tantamount to saying "I hope their careers suffer." I love Borderlands and I loudly applaud their work there. Despite all this, I hope this game fails.
