Game: Ecco Jr.

Scientific fact: the only thing cuter than a dolphin is a baby dolphin. So Ecco Jr., a prequel to the classic Sega Genesis game Ecco the Dolphin, definitely scores some points when it comes to sheer adorable charm. But it's more than just the game's star that takes a step backwards, it's the actual gameplay as well. Ecco Jr. is much easier than its infamously difficult predecessor, so much so that it often feels as if there's no real challenge. It's also very short, clocking in at around an hour. So unless you're in the mood for a quick--and I do mean quick--bout of nostalgia, you may want to pass on Ecco's youthful adventures.
