It all depends what are you looking for in the VN. For me the most important is to make decisions and have an impact on what's happening, to feel like you live another life . In 'Acting lessons' I had a feeling that my actions don't count at all.
To be sincere, I played it half a year ago, so I may not remember everything well but I do remember there were choices to develop your relations with your girlfriend or meet with new girls. There were also choices how to treat the schoolgirls. Plus a lot of beautiful women you can choose from and some interesting fetishes (consensual maledom). The relation was itself very interesting and there was also the police investigation plot. Really there was a lot of threads though not yet well developed. I really regret this game was abandoned.
You should reevaluate your rankings seriously.
Especially the following are overrated:
1. Shadows over Manston (imo, 0/10, poor plot, characters bland, i rarely say this but it's a waste of time)
2. Three Rules of Life ( 4/10, Plot shallow, characters bland, drama is too shallow yet overacting too much, characters are not that nice)
3. Bare Witness (4/10, Illusion of choice especially if you want to choose Athena)
4. University of Problems (5/10, too simple, nothing special, meh, it's average)
5. Abroad (....too short to even have a rating)
6. Esteria (5/10, meh, To Be A King is much better than this)
7. Intertwined (7/10, overrated in your list imo, but it has good potential)
8. College Kings (6/10, This is nowhere near Being A DIK. It is more like a budget version of BADIK)
9. Nothing is Forever (7.5/10, Too short to be hailed as the top 4 best VN in your rankings, but i like the story so far)
Also games that are underrated:
1. Acting Lessons (9/10) reviews are overwhelmingly positive in Steam.
2. To Be A King (9/10)
3. Leap of Faith (8/10)
4. Pine Falls (8/10)
Anyway thanks to your list i was able to play some great games i have never heard of, but yeah just want to give you a feedback that some might be overrated and some are underrated.
Well, you are welcome to make your own ranking based on your own criteria. Most of it is subjective. And I agree that it is especially difficult to rate when game is just in beginning. At first the ranking was made for my private usage but then I decided to share it.
I don't know if you've seen my more detailed ranking which I posted recently: https://vnrank.blogspot.com/2021/09/20210925.html
