Yeah, I just didn't realize what QUESTS were. I got them confused with MISSIONS. I think they just need to be more clearly labelled/delineated in the UI (I know right now there's only bare-bone presentation . I can't wait to see the sprites for the missing rivals.). I think part of the problem was that in easier modes, there's only one quest: the Graal. So I just sort of saw that as being an action "look for the graal" not that doing so is a quest and there could be other quests. Now that I play at harder difficulties it's more obvious that quests are a category of actions.
Maybe it should look like missions are stuff that's in or right outside the gates of your castle/city and quests should look like it's sending knights away (on a boat even?) and then be clearly labeled.
