In the beginning of KQ4, you need to look up certain words on page X, paragraph Y. PQ1, EGA, you need to open Sonny’s locker with the game score. I can’t think of any for the QfG series except 4 where you need the ingredients for Dr. Cranium’s potions. LSL, there’s a few. I think it might be on 5 where you need a ticket at the airport or something. On some other lsl’s, you need phone numbers.
