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.
