Deep Sea Tycoon, often confused with Atlantis Underwater 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.
