Ari is not a game developer. He is Ben’s brother and full-time caregiver, and he has been learning by building things with AI. Ben is nonspeaking, quadriplegic, has low vision, and plays with two head switches mapped to Space and Enter — that is his entire controller. Their newest game, Benny’s Ballista, is built around those switches from the first line of code.
The argument underneath the demo is the interesting part: AI has collapsed the minimum viable audience.
- Games exist for Ben, but mostly as accessibility features bolted onto control schemes that still assume reaction time, vision, and multiple inputs.
- At caregiver-evenings cost instead of studio-quarter cost, a game for one specific person with one specific access method is now worth building.
- Once it exists, it extends outward — to somebody else’s brother, student, or kid.
- Everything is free: games at switchedgames.org, a one-button-accessible hub at bennyshub.com, and physical switch kits given away to families through the NARBE Foundation.
The design stance is what makes it work. Switch access is not a mode you enable — it is the way the game is meant to be played. No interaction depends on reflexes, Ben picks ammunition, fires, and makes his own choices at his own pace, and the loop is co-present: Ari sits with Ben, watches what lands, and changes it that evening.
Two caveats worth keeping. Eye tracking is not a universal fix — Ben’s nystagmus rules it out, and his motor complexity from leukodystrophy leaves two switches as the only reliable access. And “anyone can build now” skips a step: AI is only accessible to people who can articulate an idea to a model, so the caregiver is not prompting, he is translating another person’s preferences into specs. That is the design work, and it is the part that does not automate.
