Why does this stereotype exist? Well, partly because it is a comedic shorthand. Sort of like ethnic jokes, people telling jokes create an assumption for the target audience to latch on to so the joke doesn't fall flat. Even in our "enlightened" age, gross stereotypes still exist, such as Southerners are stupid hick rednecks, whites are clueless entitlists, and gamers (or, really, ANY pop culture subculture, be they gamers, Trekkies, comic book fans, anime nuts, D&D players, whatever) are literally the Great Unwashed.
But there's another factor, and it's that we gamers bring this sort of attention upon ourselves.
The Game Developers Conference is going on right now, and one of the things they have is the Game Design Challenge. It's the gamer equivalent of Iron Artist. Some comic conventions and just about every fur convention has an Iron Artist competition, where the selected victim/artist is given art materials, a time limit, and a list of requirements, and they have to draft and draw an entire comic story right there on the spot (the San Diego comic convention, one year, managed to snag none other than animation legend Don Bluth for the Iron Artist one year. I have never been sadder to miss out on SD than that). The Game Design Challenge has the devs given 36 hours to make something based on the chosen theme. This year's was hosted by Eric Zimmerman, the chief design officer for Gamelab (the immortal Diner Dash). Three people were originally on the panel: Sulka Haro from Sulake (Habbo), last year's winner Steve Meretzky (originally with Infocom and creator of many text-based games, including the original Hitch-Hiker's Guide To The Galaxy game, no surprise his company Playdom emphasizes their comedy skills), and Kim Swift (Valve Software, team lead for Portal). Swift was pulled by Valve at the last minute and replaced by Heather Kelley (Kokoromi, an indie game company) and Erin Robinson (Wadjet Eye, Emerald City Confidential and the Blackwell series). The reason Valve pulled Swift?
The chosen theme for the challenge: make a game called My First Time.
If you are wondering, "My first time what?", please go out and get laid. After you've caught up to the rest of us, you can rejoin the discussion.
Now, video games with sexual themes are certainly nothing new. Even if you discount the stupid Mystique games on the Atari 2600, people have been making general games about sex since there was sex. And there are plenty of video games involving sex. I remember the "Nude Raider" patch for Lara Croft shortly after Tomb Raider came out. Duke Nukem had you paying money to strippers before blasting them to chum. Some unlocked the Hot Coffee minigame in GTA. Others make Flash games like Orgasm Girl, where you are an angel trying to give an orgasm to a sleeping girl without waking her up (I believe this qualifies as "rape". Not very angelic, in my opinion. Thematically, I think a succubus would be closer to the mark). And then there are those amazingly disturbing and perverse hentai games (the X-Change series is the only one I was able to play without filling my bathtub with vodka and lying in it for a few hours afterwards). But there's a difference here: these are fringe games. Games like Orgasm Girl are typically hanging around Newgrounds. Duke Nukem wasn't exactly mainstream, it was shock value intended to show the Establishment how edgy it was, like a kid writing his name in wet cement. The hentai games are imported by niche sellers, you don't find them on the rack at Best Buy (I don't count Hot Coffee for two reasons. Primo, you had to run patches and hack the game to get to it, it was walled off. Secundo, we're talking about a game series that celebrates drugs, guns, hookers, robbery, and every crime in the world. A minigame where you have consensual sex with a woman is actually refreshingly tame). This was a professional game developers' conference. Like it or not, the outside world DOES judge you by your actions. While I understand this was all in fun (and what's more, Meretzky's implementation was actually pretty interesting), it doesn't help the image of gamers as being socially retarded morons.
Just asking, couldn't they have found a more positive theme to base the challenge around?
