Hmmm, but I guess I'm also looking at the overall narrative. Like what is the MC in this story and how does the progression happen if you do some NTR stuff? As far as I can tell from the thread and walkthrough, it seems like these NTR routes are mostly self contained stuff within a core story of the MC becoming a badass or hero? Do the girls have anything to say long term about being on the NTR route?
Well they kinda have to be with so many choices. Otherwise there would be just so many variables it would be a work for 100 people.
I really like that it feels organic though. The game has a time cycle. On certain days at a certain time, npcs will move around.
You can actually see them walking somewhere etc. So if you are on an ntr route, an npcs will regularly go to somewhere to "cheat". You can usually follow them and then spy through the window if you want etc.
It is not a self contained single event, it keeps happening and you can just wander around and check up on that stuff.
The downside is that you kinda gotta play with walkthrough, otherwise you might miss some ntr stuff. The game does have in game tooltips, but that is not enough imo.
