Twisted Memories and
Restore Her Career are the best corruption focused games I've played so far.
At the moment, they are both my favorite games since I am really into corruption lately (to the point where if it's missing as a tag, I am not much interested). Sadly, a lot of corruption tagged games are sandbox or have some kind of never ending grind mechanic to them and I avoid those like the plague, personally. I just like them to be purely Visual Novel, with a lot of player input/choice - basically Ren'Py + no sandbox only for me.
Restore Her Career has insane and dark corruption, especially. Very slow burn and the MC is a complete sociopath but holy hell, the corruption in it is very nice. Am yet to play a game that goes as far and all out as that one does. Twisted Memories is just a great time all around.
Thanks for the extensive and detailed list OP, given me a lot to look through!
