Warning: Another Geizr wall-o-text ahead!
Here, Yahtzee echoes some of my own thoughts concerning the stereotyped portrayals of men(and even women) in video games. The basic point is that, no matter what gamers, game developers, and the gaming press may say to the contrary, video games still have yet to actually grow-up. Games still evince a thinking and perspective in their design which is that of a priapic juvenile male pretending to be an adult and having all the skewed misunderstandings of adulthood that a 14-year-old male would have; games still have yet to go beyond the 14-year-old male testosterone-laden fantasies. What Yahtzee describes as the manly man is much closer to the real adult male; whereas, the macho man is closer to the priapic juvenile's skewed perception of the adult male. An earlier poster put it best saying the manly man accepts and does what must be done(grounded in reality and accepting it for what it is), while the macho man is just trying to show off(compensating for his own deficiencies and unbalanced character).
It is interesting to the think that for all the "realism" that game developers like to try to push into a game(I swear FPS developers and gamers must have the eye-sight of a dog to think the monochromatic color palettes used in such games is realistic), the one area of realism that they tend to totally fail at is human interaction(the body language, the manner and subjects of conversation, and the responses to situations). I can only blame that on the geek culture's lack of empathy in social situations and the overuse of cameoed/canned jokes, potty humor, and geek culture references.
Let's be clear, however, adults have their fantasies too, and it's not all about sex(though it does come into play every so often). However, adult fantasies can tend to take more depth or be more simulation oriented toward particular situations, a vision of the future(personal, familial, or societal), a utopian dream(such as finding the perfect relationship), or a state of permanent perfection of being. Sometimes, the fantasies can center on more base desires for riches and domination; other times, these fantasies can be exploratory of other possibilities of existence. Of course, I have to admit, that the dream of being a kid again is definitely on the list of adult fantasies.
The point is that the adult mind and outlook is far more, and far from, being some indifferent badass that blows shit up all day and has copious amounts of sex. That image is a ridiculous sensationalization portrayed in the media. Unfortunately, the 14-year-old priapic male does not have the wisdom of experience to separate the fantasy from the reality, which may explain some disillusionment people suffer when moving into adulthood(disillusionment, burnout, and even some depression can be caused when our fantasy expectations of reality are not met by reality; reality is under no obligation to adhere to our ideologies or whims).
