As seen in this trailer, Nintendo's Endless Ocean game for the Wii lets players swim through the depths of the ocean using the Wii remote, guiding their character using the pointer's cursor, visible as a bright blue dot. Players can also interact with fish or plants, in order to discover new species and build up their fishy "fish log". And they can even befriend companions like a dolphin, which will become their partner and with whom they can train and swim.
