Endless Ocean Luminous is an underwater adventure game about peaceful scuba diving exploration. Like the original Endless Ocean game on the Wii, you explore the seas to find creatures and score points. It stands out for how enjoyable it is to just swim around the underwater landscape that changes with every dive, either on your own or with lots of other players online.

You play by moving a scuba diver through the ocean in search of marine life. It's easy to get the hang of since you can spot many fish straight away without much exploration. You don't have to worry about any danger or dying since you don't have a health bar. If you want, you can team up with other players online to explore the ocean together.
As you progress, the scale of the game becomes clear - over 500 different species of marine life can be spotted. Along with the real-world fish, there are mythical and extinct creatures to find lurking in the depths, if you swim deep enough to find them.
This results in a meditative simulation of what it's like to be a scuba diver without the danger of being eaten. You swim amongst dolphins, through coral reefs, and over skeletons resting on the seabed. The beauty of this game is in simple observation of an ocean's life and history.
