What’s stopping us from making smellulators, for games or movies?
Vietnamwar videogame: smell of napalm in the morning.
The sims: baby pooped.
Survival game: that lump of flesh is rotting.
Smell you later
- Images flash by and disappear. Sounds may resonate a little but are basically gone as soon as you stop making them. - Smells linger. - Imagine the cattleyard smell still hanging in the air when the scene has changed to milady’s boudoir, or to the fancy restaurant. - good point. 
 
- Technologically, nothing. They’ve even been made before! (Japanese scientists even made a device that would let you taste things!) - The problem is, nobody actually wants to buy them so nobody is making them for people to not buy because that would be a waste of time and money. Knowing that death and sewers are super common in games, I can’t say I would want smell-o-vision myself. - Do you have a source on that tasteulator? 
 
- Too complex, too many inputs needed, it would be a proprietary exploitation product nightmare like liquid ink paper printers, initially bringing such a product to market would make it cost a fortune, and it would need widespread adoption before the economy of scale could kick in.
