A few of my favourite in case someone visits this thread in the future are
Harem Hotel: In the mechanic side, it can have a LOT of improvement, as the early game is overly slow and the money management seems taste less evenin late game. But(most) of the character ended up being endearing to me one wa or another and the story got me genuinely hooked, besides the porn side is very well animated, it's not milf city as the escenes have next to no shadows, but overall great.
Succubus affection: This is the contrary of the prior recommendation, Story is non-existent, characters are basically your common monster girl tropes but combat feels so damn good, from slowly getting abilities in the early game to having your own cusstomised build by the end, either going summoner, character action game, mage, or a combination of the three. And the scenes are what you find in this sort of game, you get defeated, you get fucked by a monster girl and bosses have a few cg's.
False Myth: If you are into Anime tropes, maybe you'll like this one. story and characters are endearing as long as you don't mind, just overall charming and fun all around. As combat goes, super simple at first but it has a decent room for strategy as the games wants more from you as it goes on, and some bosses wrecked me until I actually locked in. But don't expect to be playing with one hand, as the pixel art for the escenes isn't the best and you unlock them very sparecely, still the dialogue is good in these as it plays on the characters which is a breath of fresh air as it normally tends to just be separeted stuff from plot.
summer/winter memories: Basically a lot of scenes and overall content, if you tought "Man, I'd like a persona game that is just rising social stats to go trough events and social links" then this is basically it, except that writting is mostly horny with a bit of comedy and well... the reward is mostly porn.
DohnaDohna: This may as well be a full game of it's own merits, story is good once you get accostumed to the grayness of the MC group, writting is mostly focused on being fun while it accomplishes to lead the story in a semi-interesting way, the art is just top notch and gameplay is absolutely fun... sadly I haven't completed it because it requires A LOT of farming and a wiki open aside to make it effective, also weapon upgrade system sucks ass.
Monochrome imouto fantasy: Basically a daily sim where you take care of your sister, do fantasy quest and improve your stats, art is really good and the gameplay loop is satisfying from barely being able to do anything to finally being able to do wathever you please, still expect to suck as it isn't very lenient and may want to use cheats to increase your stats for the end-game boss so you can unlock DLC.
I still can recommend others like Aurelia(great overall), Yarimon, klee prank adventure, secret flasher sereka, monster girl dreams, etc. But I'm running out of steam for recommendations tbh, so I hope these are enough.
