As for mind control, it's my favourite genre soooo
*pulls up game library*
There's a shit ton of games with mind control, I'll limit it to the ones I'd actually recommend playing. If you like the genre odds are you've played most of them anyway. Also I'm including stuff like potions, serums, and other aphrodisiacs to the mix
A Strange Night (Not exactly hypnosis but there is the use of a crazy aphrodisiac pill)
Dark Seed Chrinicles (Dreams of Desire knockoff, but a good one)
Dreams of Desire (of course)
Deviant Desires (serums to change body type, horniness, etc)
Harem Villa (lust demon's magic)
Long Live the Princess (subtle mind control conditioning)
Lust Epidemic (potion/serum)
Lust Town (lust magic)
Milf's Control (hypno ring)
My Cute Roommate (Aphrodisiac lotion)
Superpowered (self explanatory)
The Awakening (mind control conditioning)
The Gift Reloaded (was abandoned, recently said to be brought back by dev)
