I like this stuff for topdown perspective stuff/ topdown mazes:
sword of fargoal
various pokemon games
zelda: a link to the past for the snes, (and link's awakening for the gb, and oracle of seasons/ages for the gbc, and the original zelda)
adventures of lolo
dragon quest (especially the later nes ones, and the remake of the first ones on the snes)
robotrek, and soul blazer, for the snes
warcraft: orcs and humans
fire emblem series, especially on the gba
guardian of paradise
