Unity

In Unity i have created an island with a surrounding ocean.

First i added a plane to use for terrain, next i added a skybox by going into the render tab in edit. Then i created a point light by going into the gameobject tab, afterwards i added a first-person player control from the project window at the bottom. Using the terrain, i adjusted the terrain height to create two islands and finally i added water using the basic water tool in the project window.

The image is below.
