I think I would disagree in the similarity to LttP--not that it's not somewhat similar, but because there are games that are much, much closer to LttP, and which I still consider "different." GraalOnline[1] is one example.
In fact, I would sort of call "Zelda-style 2D top-down action-adventure game with swords, shields, and various key inventory items that each serve an overworld function" a genre (a subgenre to Metroidvania games, in particular), in the way that tower defense and DotA games are also now genres.
