Achievement Unlocked: Sex! – These are some helpful thoughts about the nature of sex and marriage in video games. A quote:
What the vast majority of these games inevitably do is present relationship mechanics that distill the commodity model down to its essence-you talk to the NPC enough, and give them enough presents, and then they have sex with/marry you.
This design approach is extremely simplistic and perpetuates the commodity model of sex-the player wants sex, they go through certain motions, and they are “rewarded” with what they wanted (like a vending machine). Furthermore, when sex is included in a game, it is generally framed as the end result-the reward-of romance, rather than one aspect of an ongoing relationship/partnership.
