If you are in a rush to know about it.
The 10 Chinese and Korean FMV games that could be in S-tier, A-tier, or just B-tier, ordered by release date:
Breakout 13
恋爱单选题 (Only You)
失业了，我获得了亿万游戏财产！
Five Hearts Under One Roof
Game of Fate
Hello Love: 18 Again
Beacon-fire: Project Salvation Belles (Epic)
Game of Fate 2
晨昏线
My Journey (Steam) / Go Prince (Epic)

I have chatted with some FMV players, and everyone has different favorites for each game. The order of each game varies from person to person.
Also, if you know about Personality Types (MBTI), people with 'Sensing' have a much different view because they focus on specific aspects and dive deeper into those, while 'Intuition' types focus more on the big picture. This is what I’ve found—some players are very focused on certain aspects and don’t consider other aspects much in the game.

This tier list is meant to be more general, ranking the games based on a big-picture view without diving deeper into specific aspects. The S-tier in this tier list could be larger, as it represents the general top tier, but it doesn't include everything yet, especially since the last few months have seen a lot of games released that have a high potential to be S-tier. If based on my personal taste, the S-tier would be less.

Hey i have a question to you. Would you mind if i will make my own similar ranking with my sensations? I have different opinion about a few games and i played tittles that is not there. I think it would be nice to people who can compare opinions and find out more before buying.

For VR game, consider to try this: https://store.steampowered.com/app/2522280/_/

So, there are about 10 games that would be in either S-tier or A-tier, along with a few others that have not been released yet. Focus on those games that are reasonably priced first and are confirmed to be very good, just as I do, with many more to come.

The few games I mentioned are for those who are familiar with these games, to understand why these games are not in the tier list and these games have been popular in the past few months. Besides that, there are 6 other games with the potential to be in S-tier or A-tier, some of which were recently released, and some have been released for over 6 months and were popular during that time.

Most of the games in the S-tier to B-tier, I’ve completed with 100% achievements and plot exploration to ensure I didn’t miss any hidden content, so it takes some time to get into the tier list. I still have 3 games that could potentially be in S-tier or A-tier, but I haven’t had the time to finish them yet. The tier will include all the good and important games, but it will take some time.

If possible, maybe an always-up-to-date Google Doc or GitHub could be handy here for those that find old ranking lists on Google as well?

"FHUOR, HL18, GOF1&2 prices are high in many regions. Recommend waiting for a better discount, no need to rush. More and more FMVs are being released."
Please add the full names of the games to the list, sadly those abbreviations are not seen elsewhere in the description or comments. While I know which you mean here, it would be helpful for players, and I imagine many would be confused by why FHUOR is not in the image as I think it's the one that gained the most western popularity

To add on, both LiAA and DS are quite similar and could be considered on par; however, LiAA does not directly convey love lessons to the player, while DS is a game that showcases many love stories and lessons. This makes DS more valuable, as it is not just a game for fun but also serves like a love lesson book.

Both games feature authentic love stories, such as Shen Huixin (LiAA) and Su Yimo (DS), both depicting true love toward the MC. However, in LiAA, many players were confused, as Shen Huixin's actions often come across as bullying toward the MC, while in DS, the ending clearly explains what true love is—it’s like an angel who cares for their loved one. In the ending of LiAA, Shen Huixin also appears like an angel to the MC, and this becomes even clearer in the phone messages in the prequel (LiAA-EoY).

Besides LiAA, DS also reacts to the love stories from both LiAA and VFTP, offering twists or explanations for the love stories in both games. DS uses many of the same characters' personalities and love stories to present them more clearly and potentially provide better endings.
DS, LiAA and VFTP are all equally fun and interesting. However, when it comes to love lessons, DS is particularly focused on that, while LiAA and VFTP are more about authentic stories, with the lessons not directly shown, but rather for the player to discover

The big lesson from LiAA is that you have to be serious and quick in love, or you'll lose someone you love, as someone else might take them away.
In DS, the big lesson is understanding. You learn that your loved one also needs their freedom. When conflicts arise, express your opinion clearly, but don’t force them—give them time to think about your point of view. This is why in DS, the game often requires the player to wait until an option appears.
