Hum I dont have one but there are a few that I always get hyped when there is an update:
Pale Carnations (My favourite)
Corporate Culture
Where It All Began
Eternum
Desert Stalker
Raptus
Being a DIK
Blackheart Games Series
Life in Santa County (used to be really good until dev decided to rework the story, basically remove all incest and murder because steam realese and now its trash)
Golden Mean - great renderings, interesting story, great potential. I hope it doesn't get abandoned.
Pale Carnations,Project Myriam,Friends in Need,Light of my Life,Desert Stalker
Hands down: Camp Buddy with Ecchi Sensei as a close second.
There is no game that I´m aware of, that seriously glued me to my seat with all of it´s story, like CB. Every route. I usually don´t play multiple rounds of a porn game, but Camp Buddy, I played every possible round AND searched for a guide afterwards to get every ending. The porn/nude scenes in he game are absolutely awesome, the voice acting is perfect (IMO) and the story is amazing.
With Ecchi Sensei it was mainly the porn and the girls to be honest. I never saw another game where the girls are as beautifully made, as in this game.
