I have a 100% save for the game, with the 2nd page of save slots the first 6 locked saves are the necessary saves needed for each ending.
I would say to people definitely go through the story as the walkthrough describes though as it was my favourite way to experience it.
10/10 didn't goon...
Honestly what you're saying is true, I gotta say the most important part is dialogue, it needs to be at least somewhat genuine or like real, not like it is exactly like a real conversation, but not just static and straight to the point
