Was just thinking of this, so here it goes. No particular order.
Light of My Life : Really good story, good characters and art.
Where the Heart Is : A lot of variety and replayability.
Become a Rock Star : Probably the only game where I like all the girls
Our Red String : I like the dual-protag style and the art is good. Lot's of routes.
Dr. Amana, Sexual Therapist : Like the blue/red pathing, good characters too.
Long Story Short : My top corruption game. Good number of routes
A Mothers Love : A good story, one of my favorite MILF's
Haley's Story : My top incest game. Haley may be my favorite character.
Hillside: I always like helping out cute girls in times of need.
Single Again : I like the story, the girls are cute too.
Honorable Mentions. These games likely jump into my top 10 when they are updated.
Being A DIK : Game is obviously huge, but has too much drama.
Research into Affection: Can be repetitive, but I like the girls and the progression system.
DeLuca Family: The very long update times keep it from top 10, has the most original story IMO.
Sins of the Father : Lot's of routes, a super harem game too.
A Knights Tale : I love a good and simple romance game.
A Wife and Mother: Again, long update times. Probably my top MC corruption game.
Offcuts: Super long update times, but all the routes are fantastic. Art is great too.
DMD: One of the old originals, good routes and fun characters.
Jessica O'Neil Hard News: Good story and art. Jessica is probably my favorite Fem MC.
Basically, games that are story focused and have some variety in characters/routes.
