I purchased this game recently, and played for a few hours so far. For those who may be considering it, I just wanted to let you know my thoughts. The game has pretty good graphics, considering it's not HD. It's very laid back, and technically, fulfilling the missions is optional. You use the Wii mote in order to move your character, and the mote gestures are simple enough that a young child could do it without an adult helping them (although the missions require the ability to read). As you move your character through the ocean on dives, you have the option of swimming about, and interacting with the wild life. These interactions involve petting the fish, and feeding them. Doing this rewards you with information about the species you are interacting with. It's quite relaxing to just swim about, regardless of whether you choose to do the missions. The sound effects and scenery aid in this. I chose to do the missions at first, and got side tracked when I discovered other areas to explore. These areas turned out to be on a mission later in the game, so it was helpful to explore. The only constrictions are that you have a limited amount of oxygen, so you do have to surface occasionally, when the O2 meter indicates you are running low. Overall, I think this is a good game for someone who is not interested in any pressure to complete missions. I suspect a lot of hard core gamers would find it pretty lame, unless they were using it simply to unwind. It's not likely to challenge anyones skills, but sometimes that can be a good thing? I think it may be a good game for young children, (or others), who get frustrated with the more challenging games. It may also interest those who like to learn about sea life, and enjoy things like National Geographic, and Animal Planet. Hopefully this will help those who are considering purchasing the game.
