Sorry I was running out the door to go somewhere, but tried to do a dot point summary - I'll do better and slower next time
We actually don't know if there is any NTR in the canon. If it can be turned off, I'd assume that means it's all optional NTR for those that are okay with it. THe thing is that it is a darker and more intense story in regards to relationships. In SG, you get to build new relationships, in WiaB you have to mend broken ones. I'd suggest trying it anyway, as it can be turned off.
WiaB is still set in the past - Ocean is developing them concurrently, but they are still separate times. The protagonist generation in WiaB are older in SG (and we don't know much about them directly as yet). I would highly recommend trying WiaB as it is now with the NTR turned off, as you'll still get all of the actual plot. Even with it turned on, there is currently next to no content that would trigger anyone, so you're safe to at least understand more of the story. NTR isn't my thing either, I'm just going to play making the best kind of choices for the kind of person I am. If I get NTR'd by an AVN, I guess that tells me a bit about my own choices and I need to make better choices
Regarding the length of development - I want it all now of course. Maybe tomorrow at the latest. But I'd rather know it's going to be developed the right way rather than rushed. The overall depth of detail is what makes this game stand out - there are stories playing out in the background of scenes, and there is so much to absorb. The upside is that Ocean is pedantic enough to persist making this. Think of it like a comic - there's always a new episode. Readers of Marvel comics still don't know how it all turns out. I doubt it will be that level of endless, but Ocean has big plans, I can sit and wait and do other things in the mean time, and get excited for each update.
