Keep in mind, Acting Lessons, Being a DIK, and Leap of Faith, are all basically ROMANCE games with NO poly/Harem paths.... Faith kind of DOES, but it is limited, and HARD WORK, and basically, something like DIK, which has two paths, basically a Good Guy v Bad Guy thing... still becomes a forced Romance even when you are bad guy.
I found DIK to be the most overrated AVN I have ever played, personally... because you are hardlocked in a Romance ending no matter what. You go the bad guy path, and focus on the bad girls...and you THINK that will open up a couple of twisted hotties as bang buddy babes.. and possibly lead to a poly/open/harem ending... it does NOT. You have ... what... four endings? All romance endings, with ONE girl.. well in one of the four endings... it is TWO girls... but it all Romance, no matter even if you play the Bad Boy style, and go for the bad girls.
Desert Stalker is awesome, but still in development, and you get teased, but blocked from Elf Pussy... and there is some Elves... so one should ALWAYS get Elf Pussy. BUT ...I would still maybe say give this one a try, unlike the rest I discuss here. But the hottest babe in the game, is an Elf.. and her 'housemate' the second hottest... both Elves.. and you cant bang them, that deserves some hate, and something one needs know before they jump for the game. Because Elf Pussy is the BEST pussy in any AVN, everyone knows that.
Astreon, is a LOT of game, and VERY VERY visually lush, beautiful graphics and aesthetic.....BUT has almost NO Adult Content, the story is very convoluted and unclear, and goes out of its way to try to be mysterious, which means also, confusing....and the women who are meant to be LIs, are mostly bitches who are total cunts, with the exception of one Space Elf, one Cat girl, and one chick from the MCs old life who has big time crush on him. All the rest are just total bitches who are about as endearing as syphilis. The MC also has almost NO Agency.
Acting Lessons is even more kinetically linear narrative than DIK, by the same guy.... but even more of a forced Romance than DIK, and the MC has even less agency, when all is said and done than Astreon. You will literally have the ending the Dev wants the story to have, with someone alive, or dead, or somethng... how happy it is the only thing that can change.
Chasing Sunsets is a forced Romance with just two Love Interests, and no agency at all, and minimal sex scenes, offered as reward for playing the game as the devs intended. In fact, if you DO NOT make the right choices, and play as they wanted, you get an achievement 'You're better off playing another game"... and the MC might even die. Trash.
You have to be very very careful... a lot of AVNs are ROMANCE games, at best, or narrative efforts, by devs that think their Edge Lord story is just the be all and end all, rivals Shakespeare, and the sex is tokenism, paltry, and poor quality where you have fuck all agency, and are pushed down the devs idea of 'how you are meant to play', some even with hard lockouts and dead ends as punishment for NOT doing so. There is little agency, a small selection of women, often single serve encounters (you do not build a sexual relationship with a woman, you bang her once, and on to the next), short poor scenes, and back end loading of them at end game as reward for being a good little reader and reading their story. They truly SUCK. Hiding behind being 'Story Rich' for their abysmal failing on the adult content side, claiming 'its not that kind of game'. In fact, many could have NO sex scenes and it make NO DIFFERENCE... and the sex scenes are included JUST to milk the fact Sex Sells.
Many of those recommended are just that.
Race Of Life and Ripples are PEAK though. 5 Star efforts, though VERY different games.
Pale Carnations is unfinished but I say PEAK, A House In The Rift is peak too. The Peakiest Peak of Peakness though, for a pure sex romp AVN, is Isekai Paradise, a sleeper God Tier AVN.
Race Of Life is on Steam though, I do not know if it is here.
