You can find a lot of 3D yuri games on OP main post.
However, my opinion about this is that Yuri games often involve a lot of romance, and romance focused games aren't really popular in the west compared to the east.
Which means that most of the developers are from the east and those doesn't really use Daz3D as much as western devs.
I don't know how far I am from reality, that's an interesting question.
I don't know if you're putting futa games on this account or something, but I really disagree with you with all due respect.
We are in a topic about yuri games and you can see that even the 3D ones in the first post, are either 3D from illusion games (Honey Select or Koikatsu) and games with 3D sprites like Being a Dik are more difficult to find (and even fewer are those that are similar in quality to a Being a Dik).
For every 1 3D yuri game there are 5 Illusion or 2D drawings games.
The issue, for me, is that if you look at yuri games threads they have a lot less discussion and comments. I imagine that means there are less supporters on patreon or something, which means less money for the game. I think it's worth enough for devs to invest in 3D models (and customizing them should pay off even less) if they can download a Honey Select here on the forum and use the photo mode to create an entire game.
For me, it's personal preference. Well-made Daz models look great. Badly made ones nosedive face-first into the uncanny valley and dig for days. And from the number of those I've seen, it's really easy to get wrong. Illusion girls don't have this problem.
Here comes what I said: games with DAZ (is that right? Are those 3D called DAZ?) are rare, the ones that have are kind of weird (there's no "Being a Dik" lesbian) and the staff, maybe because there's less patreons and resources, prefer to get the illusion sprites that are already ready!
