Anthesis. Great game. You can see where the corruption for shimobashira started. Not much reason to replay. You can see the foundation for ambrosia and magical girl celesphonia
Probably all xxx games will end up on this list. Just their level is not very high to spend extra time on them, and new projects appear every week - there is a lot to choose from.
Summer's Gone. The dev dragged it with the reworks and now he changed things made it more sfw, removed scenes that are crucial to characters personality and biggest turn off is he nerfed my Bella's anger issues which made her unique to other characters.
Also i think when he tried to connect WiaB to SG is what ruined the narrative. He tried to add many unecessary things in the early episode rework just to squeeze in other characters that might be connected to wiab
On this website, you need the "member+" rank to get the game. Alternative, you can find the game on the website-that-shall-not-be-named (but it has "F", "95" and "zone" in the name). However, the version here has a few scenes that are unavailable over there. Both have the bestiality impregnation.
evenicle despite actually having good gameplay, it it is the biggest slog I have ever seen in a hgame. Not only grindy but the story just goes on and on forever. It took me over 50h to 100% it and the content is very tame and mediocre. I will not even consider playing the sequel.
To me good written AVNs are Pale Carnations, A house in the rift, amd the mist. The dialogues aren't stiff and felt natural. The characters habe their own unique personality also which almost majority of AVNs fail to capture.
