Console: Sega Game Gear
The intrepid aquatic mammal undertakes a rescue effort that brings him to the far reaches of Earths oceans, to the remains of Atlantis, and even back in time, until he confronts his alien foes. From the plot to the color palette to the music, it was intriguingly strange and bizarrely new age-y. It really worked as a game. There was something beautiful and exciting about playing as Ecco, snapping up fish and leaping out of the water with a flourish of your tail.
