In my experience the former is far more likelier and happens more often than the latter. I have a lot of good and useful feedback, be it praise or critic and you cannot escape the critics for critic´s sake.You worry entirely about the fans becoming entitled if they think Eva will listen to them, but you completely ignore the risk that by releasing a half update now the fans will feel entitled to future content updates at a faster pace than Eva can deliver them. That, IMHO is the far more pressing risk here because, again, Eva is so obviously struggling to write this game.
But you learn over time that in some cases both praise and critic are just vehicles to push the point of view of a specific person. I had feedback were the the only hidden, but aggressively pushed point was that I was not writing the story exactly like they wanted. If you bow to these "fans" or critics, you are lost and may heaven help you, because then the story is not yours anymore.
Entitlement for faster releases is very rare, especially if you tell and explain openly why you make the intervalls you do. In Eva´s case here your point on this is extremly moot, since anybody not powdered with the clam satchel can see that Eva has writing problems and is far behind her own schedule. Which is the point why I argued for a release of the Ian part, it would have been a life sign of the game!
I too respect your opinion, I simply argue from my experiences as a writer. Eva is in one of the worst situations one can experience: the part you work on is not coming together, no matter what you do. I know this feeling as well.You clearly disagree and I respect that,
There are chapters in your work which practically write themselves, you see them in your mind´s eye and they come onto the paper exactly like you intend and want them to. Then there are chapters which are work to be done, nothing too positive or negative about that. And finally the chapters which are nothing but a horrible grind! You know what you want, but it does not come onto the paper as it should.
