Do you have a list of what you've already played? Have you finished the popular sci-fi/mystery series (Zero Escape/Danganronpa/Steins;Gate)?
Off the top of my head
Nekopara - Didn't really like this one. The game despite seemingly wanting to set up a story and world of some kind it went absolutely nowhere with it. In the end the entirety of the plot just felt like a shallow set up for fan service.
MGQ - I was drunk. Let's just leave it at that
Sunrider Academy - This was ok but a bit shallow the management stuff was interesting at first but ended up being grating as you went weeks without anything really happening story wise. The difficulty was also weird as I was constantly changing it because the game had ridiculous spikes caused by random negative elements along with intentional ones piling up and putting me into a death spiral multiple times.
Sunrider Mask of Arcadius - This wasn't half bad for a free VN I liked the strategy elements but it did feel unbalanced in several spots. Story was so so
Katawa Shoujo - First Visual Novel absolutely fell in love with it. I feel like there's a lot it could have done better from the choices being somewhat arbitrary and the limited interaction and art assets but the characters and story was just so good.
Kamidori Alchemy Meister - I never finished this but I really liked what I played of it. I always enjoy VN's with a bit of meat to the gameplay. Also liked most of the cast despite them not getting a ton of screen time individually.
Dangan Ronpa 1/2 - Pretty good: strong art style, memorable casts, and interesting story was a highlight. The story did sometimes devolve into stupidity though with how the plot twists were set up.
Trillion - Ehh I finished it but didn't really like it the fact that almost every love interest was blatant incest and the ending you got was decided by which character you finished Trillion off with really turned me off of it.
Fragments Note - The story on this was fairly weak despite its interesting setup and the fact there were only 3-4 real choices just kind of made me eh on it.
If My Heart Had Wings - Played this but only finished one route. It left a fairly strong impact on me at first (even had a brief stint where I really wanted to ride in a glider) but after a few days and looking back on it objectively it was great but not mind blowing.
Da Capo III R - My most recent one. Adored the characters and world. The twist after the opening where you go to Weathervane and find out the protag is a high level mage hooked me. What happens after you finish all 4 routes blew my mind I ended up staying up later than I should because I couldn't put it down at that point. Giving a narrative justification for multiple routes and playthroughs I thought was absolutely brilliant. The game also had enough choices with how you spend your time to scratch my itch for a bit of gameplay. Also helped flesh out the world as some of the choices were actually meaningless in the sense they did nothing but give you more insight into what the side characters were doing/thinking.
