Ya know, after years of playing these games I've found most western devs of adult games fall into 2 categories:
1. Have successful patreon and milk as long as possible
2. Wish they had a successful patreon and cancel the game
Usually starts with a promising tech demo with a promise of content, maybe a good cg or two. If the ball rolls usually get 2-20 or so scenes, then it devolves into "technical" updates which generally involve tweaking and balance every month to "show" some sort of progress that tricks people into thinking they are actively working on something.
If you want completed games, you just need to find the few western devs that actively complete projects (azurezero, Remtairy, Vortex00 or I'm at a loss because it's so infrequent). It might be a fine idea to compile a list of developers who complete projects (or have a product that may as well be complete) and use that to keep track of who would be worth having clout with the community.
Or just play Japanese games since they tend to always complete their work, even if the quality ranges from really good to complete trash; at least it is generally in a complete state.
