Fergus, Hierarchical Games in the context of the index heading are games like Stratego or The Jungle Game where there is a capturing heirarchy (A can capture all pieces, B can capture all pieces but A, C can capture all pieces but A or B, etc.). There aren't a lot of these games in the system, but we do at least a couple.
