After reading mainly positive reviews I thought this sounded like the sort of different game i'd like to try and once i'd got it home and loaded it up I wasnt wrong.
Starting with the basic training features you are eased into the beautiful underwater world, which is viewed through fantastic graphics - probably the best I have seen on the Wii so far.
Once you get the hang of the fairly simple controls it is great to be able to swim around and explore the ocean and interact with the sea life as well as gaining knowledge of them.
This really is not a game for those of you who have to constantly be racing/shooting/completing missions - I really think anyone who falls into this mould will be very bored very quickly. I myself, even though a big fan of action games, found this to be extremely interesting and relaxing, and is the perfect way to spend a few lazy hours crashed out in the armchair.... overall (imo) a great and novel game experience.
