SKA was one I had only the tiniest hope for, going in, that it wouldn't be yet another RPGM female-protag game with MC being raped and/or blackmailed to promiscuity. Ironically the fact it
didn't have a "completed" prefix made it stand out from the crowd. Turned out to be the best damn slow-corruption game I've seen, as long as you buy into the premise of incremental mind-control coupled with social finessing by the deuteragonist/antagonist.
I can't stand VNs anymore due to the lack of gameplay, but when I was playing them, I thought
GGGB and
KoD were top-notch female-MC games.
For something a bit more open-world,
Dilmur and
Defenestration also made a good impression, though I haven't played them recently.
Ruin Me was a nice find, good writing coupled with a Lovecraftian theme you don't see often made that evening enjoyable. Sadly the dev seems to have gone MIA recently.
Naked Ambition is interesting, in that it plays a bit like a roguelike, with a semi-randomized event order, card draws and skill checks. The player doesn't have full control over what happens - what you do is advise the princess and set her training schedule, and then RNGsus has a say as well.
Finally,
MvS is a female-MC trainer game where the protag is just as slimy and conniving as your average male slave-trainer MC, probably more intelligent too. It's light on gameplay, but enjoyable for the writing and story if nothing else. I think the slave-training part takes a backseat to the court intrigue stuff.
