I played the first game and it was pretty enjoyable and I joined the discord years ago, but I was never able to find a FAQ about how the routes for the first games were going to be handled going into the second?
We got pretty divergent character paths.
The game asks a bunch of questions at the prologue, and when meeting some characters that have divergent routes the first one usually a prompt asks you what happened during the events of the first game, something like:
1. I know that person
2. I have a physical relationship with that person
3 I never even met that person
