"Video games are one of the most powerful mediums for active fantasy fulfillment as well as learning about one's own desires without any of the shame, rejection, fear, and sometimes simple unavailability of real-life sexual encounters," according to Zsuzsa James, a co-vice chair of the Romance and Sexuality in Porn Games group of IGDA. "Compared to porn, games provide the possibility for player agency that can feel very empowering, not to mention the sheer amount of potential variety for lovers and erotic situations that wouldn't be practical with real actors."
And unlike the fugue state many of us enter while passively consuming videos on a tube site, the interactivity and fantasy scenarios in an adult video game can allow for more active exploration of your sexuality. That's especially important for folks who don't see their desires reflected in regular mainstream porn.
There's even an indie sex adult game renaissance of sorts in the making. On platforms like Patreon, top free adult games have thousands of fans paying monthly subscriptions to support their favorite creators.
There are hundreds of thousands of sex games on the internet, with dozens of new ones cropping up every day. But there isn't a good all-encompassing central place to discover all their varieties. Censorship also holds adult games back in terms of their ability to reach a large audience, which continues to be an issue on major platforms like Steam to this day.
