Dquin, I see that you put time creating your post. Respectfully however, I do think you're trying to read too much into it.
GGGB is just a game, an adult one -- an H-game -- at that.
Too much exposition about background information especially about characters' thoughts, motivations, and prior history to make them what they are now in the story
will often have the opposite effect and hinders the overall quality of a game.
Yes, some exposition is important and many games fail spectacularly at that, but players also do not need reams of pages why certain choices are present and going too deep into the thoughts of a character. (A dev could potentially take away player agency if they do.) Likewise,
of course, you'll feel like there might be "a lack of depth [of the given] choices", because this is not a free-form, sandbox game. It's a visual novel, a
CYOA type of game. Even if it wasn't, there will be some limitations imposed
to keep the pace flowing in the story while retaining its entertainment value.
Eva had to juggle many variables and paths while also having to wear many hats. As an independent developer, Eva had to be responsible for the writing, the coding, the art, bug fixing, and so forth all while not getting bogged down by one thing or another. Ultimately, this is an
adult game and the story
has to move forward to (arguably) the most important aspect of these types of games --
the action.
It's a testament that Eva managed to get the game to a finished state considering the complexity of
GGGB in comparison to other VNs. Many of her peers have failed to reach this achievement on simpler games, and in fact will never even get close to such a state. You can try the other game that Eva is developing, found here:
Our Red String. Eva has improved as a developer over time so you can see firsthand what that "passion" has brought. If nothing else, the art has improved and it isn't one of those cookie-cutter ones often found in other games around F95.
TL;DR - Too much or too little exposition is bad. Balance is important in getting to the action (aka, the sex scenes) and making them meaningful within an adult game. Eva has another game,
Our Red String, which is currently in development. Found here:
