LTTP is incredible, by far the best of the 2D Zelda games and sets the standard for all top-down adventure games that came after. Even today, there are games being made which are clear homages to this classic. Great difficulty curve that makes the game feel challenging but not overwhelming and a beautiful open world to explore - like many GBA games, it's a remake of a SNES classic that works amazingly as a handheld. Go play it if you haven't yet.
