Well, that's one "puzzle" (three gates at the power station). By "puzzle" I meant something like puzzles from SH3, for example. AW is not that kind of girl, though. More story/dialog driven, with combat throwing in, like sudden deus ex machina, or "filler" of some sort. Because, they change game from original free-roam adventure, to linear thingy, but story stays the same, I guess.
