Long comment but here we go...*deep inhale*
Eternum (The number 1), Once In A Lifetime (Also made by the guy who created Eternum [not required but definitely recommend playing Once in a lifetime first as it slightly connects to Eternum]), Sicae (great avn also by the same person who is making My Bully is my lover), My Bully Is My Lover ( ik weird name but it's not how it sounds, it's actually gas), Projekt Passion (insane graphics, amazing story, superb voice acting, characters you care about), Cosy Cafe (if you into slightly dominant harems), Pale Carnations (if you like a bit of dark in your avns, highly recommend, and Hannah is just *chefs kiss*), Last Human (if good graphics and nekos are your thing), Oppai Oddessy (superb graphics and story sci-fi themed), That New Teacher (exactly as described [you're the teacher] great graphics relatively new an if I recall) Ravager (VERY different from the rest, you play a dragon in a....it's hard to explain, but very story rich and lots of choices that matter) Ripples(Holy fuck what a great storyline, nice characters) Fates Collide (Good, a tad bit short but still being updated.), Adored By The Devil (great storyline as well, and ooof your lil red head friend), Young Again (decent storyline LOTS of content Grace best girl)
*Long exhale*
I hope I have spoiled you as well with these gems. They all have graphics similar to this one if not better, hopefully you at least see this message once and try some (or all out). Imo these are the best of the best on here, might be some I missed too but those I listed came to my mind immediately.
Enjoy the genre and may you find further great avns.
