See, it's not weird that people will call these comments out if you say there is no new content in 4 years. New content I can think of:
there was no spider scene in the original, no sexy animations with Miru with nerf guns, no dart scene, no bashing a Krayt member in the toilet, no Dana at the pub, no Daphne at all, no Dani, no Monica that I remember, no drug laboratory, no Emilio, we never saw Leia's club in the pre rework. But nothing new... have you compared them side by side? Although the story hasn't progressed past the points it previously got to, it's also gotten broader in scope and it's not following the same plotline in a linear fashion, and has set up a lot of the plot more plausibly than the previous version.
The people who say there's no new content either mean - there's no new sex partners and they're bored of Miru (heresy) or there's no lewd scenes with their preferred LI (well, yeah, but the scenes in the previous version were so painful to look at until after the camping trip, so more of those animations will be better) or there's no new content for their fetish. But there is a significant amount of content that wasn't present in the original. But the development is slow and the story hasn't gotten past an equivalent crisis point, so there's nothing new, right.
And some people are bored with conversations, and should find a game with less plot building.
At least have a compelling argument as to why all this new stuff doesn't exist when it clearly does. What most people seem (legitimately) pissed over is if they supported him based on the original and they don't like the direction that world-building-Ocean is going, because he pulled their preferred story away. It's because it's missing the ninjas right? I can understand that.
As far as the pacing of development goes, either you have patience and do other things while you wait, or you don't.
I'd not wait that long. Someone can correct me, but it's 3 chapters in to about 30 planned? Might be less for WiaB than SG - that's why they majority of people are screaming about the time of development. That to me suggests play it enough to see if you want to keep it on your watch list.
My suggestion - it'll be broken up into seasons, wait for a full season one release, then see if you like it and have the patience to do other things while you wait.
