I am trying to go to the alternate path in chapter 3, the path that requires you to gain 10 LP. The problem is that I can never ever gain 10 LP no matter what I do. I am following scrupulously the FAQ at GameFaqs by Rufas Wan (there's only one of them).
The game refuses to give me 1 LP after question 1-6 (go with Gijumu's team), and after Question 2-2 (you insult Lena in the jail). This makes me miss 2 LPs at the start of chapter 3, and no matter what I do, the game will never give me those 2 missing LPs.
EDIT : I checked on the original japanese, and the same problem appear. I really don't understand how one is supposed to reach the alternate path in chapter 3 ! Are you supposed to import LPs from Suiko Gaiden 1 ?
