Every time something new about this game. Quite a small window of opportunity because I only have three out of five chick choices - I basically go with Tommy to a bar with fake ID and kick the jocks out of the party on most runs.
Maya and Josy Dik run is very easy, same thing - during the scene in Ep.4 be Neutral, and then go all out, becoming a bad guy.
The most exotic path is rejected by Jill. It's quite difficult there: you have to be a good guy at a picnic or during scene in a mansion in Ep. 7, I don't know exactly. I can't tell the final moment. But then level up to Dik, which is a very small window of opportunity - you need to keep an eye on the balance and remember that 10 or more Dik/Chick main choices will eventually give a permanent Dik/Chick affinity, that is, you need to be close to this border zone.
Further: no other paths should be opened with other girls. Otherwise, the game immediately resets you to them and closes the option to choose Jill during the final selection in Ep.8. And of course I can't see that scene where Jill refused to be with MC.
And then I realized that this is impossible for me, because Sage is ALWAYS open to me. I tried, honestly. Tried to refuse her to learn to play the guitar, tried to leave after a movie night with HOTs...but looking at her face I always rolled back.
In the end, I just asked people for saves and saw what the consequences would be.
