Arstechnica: "Endless Ocean is the physical embodiment of Nintendo's "blue ocean" strategy; a game that appears to be targeted directly at people who don't play games. Unlike most traditional video games, Endless Ocean doesn't have much in the way of goals or challenges, and those that it does have can be ignored. And therein lies the appeal of the game.
A scuba-diving simulator in which the player can travel around and explore at his or her own pace-with few exceptions-Endless Ocean is one of the more relaxing games on the market. None of the animals offer any kind of danger, and aside from a few equipment upgrades, the entire ocean is available to be explored almost from the very beginning".
