The newest in that list is actually Talothral's latest VN,
Tribulations of a Mage, from December 2023,
and Terminus Reach: Sentinel 2 is newer than Parasite Black btw. And if you meant Caribdis's debut
Once in a Lifetime, his latest VN
Eternum is an obvious 1 to try (I recommend 0.8.5 for the music before the rights holder pulled the rug out by changing the terms).
That AI stuff dominates the latest updates because a few "big" titles are updated pretty often. That means it takes more effort to find good stuff in other genres that often have longer update cycles. It isn't really crowded out, but it gets pushed off the first page pretty fast.
I'm sure you'll be able to find new stuff, newer than the VNs I linked, if you go
here and open a
seeking request for recommendations. Just take a moment to write out your preferences and hell no's and titles you already played.
You're still getting on the list though...
