5. Ecco the Dolphin: Defender of the Future You're a dolphin with telekinetic powers on a quest to rewrite history and unite dolphin and humankind with the healing power of song. Oh yeah, and the humans sent the majority of dolphins into space. Essentially, this means swimming around in an unimaginably hard 3D environment and slamming your needle-nosed head into unsuspecting sharks. It's kind of like Ferngully with dolphins. The aliens from the original Genesis titles come back and try to subjugate everything, and whether they get taken out or not is all up to a time traveling dolphin and his magic powers.
