Xbox Live Indie Games was notorious for a best-seller chart that was dominated by ‘massage’ apps. These just ran the rumble continuously at a selectable power. From this I infer that someone, somewhere, was managing to get themselves off using vibrations from a 360 controller*.
Vibration seems like a promising addition to a fetish game. Not that I’ll be adding it to Fleshcult in the foreseeable future: there’s no web API for force feedback. But still, I started looking into what I could achieve with a native app.
