IMHO one of the best mind control games is actually in a Fire Emblem style SRPG studio game called Aldo Senki. Unfortunately, barring from a subpar MTL, the game is largely in Japanese and the translated portion doesn't even make it to the gaiden part where the game elevates even further. It's a shame because the game is IMO THE FIRE EMBLEM MIND CONTROL GAME in the sense that it feels like the story is ripped from an older Fire Emblem game from Kaga's era but with mind control and corruption as the big themes to the point that there are genuine parts of it that I feel it does better than even the mainline games. Also, be aware that the game is definitely more story focused than your typical ero game and is definitely more of a Fire Emblem first, Mind Control second type of game well at least until Gaiden where its a mix of both.
The game is free on Pixiv but again the Gaiden portion of the game is untranslated.
- For games that feature SRPG style gameplay theres the pervyfantasy games which include Forbidden Book, Paraworld Heroes and another one whose name eludes me but are all greatly inspired by Aldo Senki.
-
Azure Orphanage which I believe features mind control in one of the character routes.
-
Chastity Sentai is a Power Ranger Style corruption game.
-
Third Crisis is another corruption/mind control heavy game with an SRPG style
I can mention more games that feature mind control style SRPG such as We are Bandits which is basically a parody of Fire Emblem but those are all in Japanese unfortunately.
