I’d like if controllers had essential oil diffusers. Say like a cartridge that contains 16 scents. You’d buy the one for a particular game.

Probably make more sense to have a separate device wirelessly setup to release the scent for each level.

I know this was thought of years ago and it’s an impractical idea. But I’d be for it. I don’t want tire and gas smells in GTA. But hooker perfume would be nice. Or air freshener for your favorite ride. Luxury plane have the “new” smell. One area might smell like cedar. Another area could smell like mint.

Never gonna happen but it’d be interesting.
