I agree Eva's games fall into the trap of following a strict "release cycle" development plan that often loses track of what would work best in terms of a full-fledged product. But that's pretty much the only thing I agree with, everything else reads like an extremely shallow read of most characters and mismatched expectations of what you think the story should be and what it is actually trying to be.
Also I'm just confused why you are compaining about the game's story under the argument that "Eva can do better", she made ORS, which you are currently ranking as "below average writing" in a porn game forum, and GGGB which, in relative terms, is much more riddled with stereotypes and characters that are bland representations of generic fetishes. It just sounds way more that your taste doesn't mesh well with Eva's writing than it "failing to live up to its potential".
Ultimately Eva's games are kinda like a season of a 90's sitcom you kinda liked, the characters are there to fulfill very clearly defined roles while still having some charm of their own and the story is pretty much slice of life. It is a comfortable and fun thing that works well as long as you're not looking to be challenged by it.
