Link's Awakening on GameBoy.
Besides the fact that I think it's one of the best games ever made, it's technically out of this world. I still can't believe this existed on GameBoy. The game is vast with many extras and even has a fairly elaborate story. It includes an endless array of completely different environments, characters, enemies, items and other objects all with their own unique sprites. There's a plethora of effects in those sprites and surroundings to liven up the experience and on top of that, this game has actual cutscenes! Real cutscenes, on GameBoy.
This game has so much, it puts it's 'big brother' on the SNES to shame when that game doesn't have most of those things. And the GameBoy beating the powerful Super Nintendo, that shouldn't have happened.
