Represent entire series of Deep Sea Tycoon games. Deep Sea Tycoon is a 2003 video game developed by Anarchy Enterprises and published by Unique Entertainment. This game involves you building an underwater city in 3D. It has a sequel, Deep Sea Tycoon 2, developed by Pixel after Pixel.
The gameplay of Deep Sea Tycoon involves choosing one of 24 different characters and creating an underwater city filled with different buildings and features, from Mermaid Palaces to Seafood Restaurants. Through the character they choose and the choices they make in their city, the player can become a ruthless oil-tycoon, or something similar, or an environmentalist.
The gameplay is similar to Moon Tycoon. The player creates buildings on a flat piece of land, that must be connected to other buildings by a "tunnel". The only major differences is the scenario, and the types of buildings each game uses.
