Star Knightess Aura - Looks like a typical rapey tentacle-filled Japanese RPGM game at first glance. Is actually the best slow-corruption and brainwashing game I've played of any genre. No rape, no tentacles, and while the anime influence is strong, the dev mostly avoids the cringeworthy tropes I hate in ero-JRPGs. Status: 20% to 1.0, so don't expect the sexual content to get too spicy yet. Still absolutely worth a play if you're into the aforementioned themes and don't mind some challenging RPGM gameplay.
iNSight of you - almost entirely animated and one of the best maledom trainers out there. Also one of the funniest games I've played, ero or not. Status: Not far from completion I think, got several hours of content to it including the gameplay.
Corrupted Saviors - If you don't get driven away by the complete lack of graphics, the learning cliff or the difficulty, you'll find what has to be the most indepth non-con corruption game ever. Unlike a lot of other text-based games, it doesn't take a "everything and the kitchen sink" approach to fetishes, and the quality of the content is better for it. You get a range of personalities to break, a number of ways to break them, and once you do, you can watch them abuse each other too as their sanity unravels. It really does make you feel like a sadistic overlord savoring the heroines' downfall. Status: You can play a full game against a randomized or customized team, and use the training system, but the campaign mode is in its first iteration.
Accidental Mind - Another text-only game, this one is one of the best in terms of mind-control, albeit more benign than most. Personally I couldn't get over the lack of proper gameplay aside from the puzzle elements, but I have to applaud the quality of the writing and the implementation of the mind-control fetish. Status: in-development, not sure how much the dev still wants to do but there's clearly a ways to go in terms of story.
Simply Mindy - Rare example of a female-protag game that's not really about corruption, iirc the MC is plenty familiar with sex from the start. Funny and one of the nicest-looking pixel-art games I've seen. Status: Completed.
Pyorgara games - These are pretty unassuming, and generally their gameplay is flawed (though improving with each game), but they do a great job with the maledom and dubcon themes.
