Ecco the Dolphin (エコー・ザ・ドルフィン), frequently referred to simply as Ecco is a successful video game developed by Novotrade International and published by Sega for the Sega Mega Drive, Sega Master System, Sega Game Gear and later Sega Mega-CD. It is one of the Mega Drive's most well-known titles, and spawned numerous sequels. The game features a bottlenosed dolphin named Ecco on a sidescrolling underwater adventure.

Gameplay

The game is noted for its high difficulty level, and though appears to appeal to a younger audience, has a much deeper and darker story than anticipated. Ecco on the Mega-CD features a full redbook audio soundtrack composed by Spencer Nilsen and has re-designed levels.

Development

Ecco the Dolphin was inspired by the works of American scientist John C. Lilly, particularly his attempts to communicate with dolphins. During the 1970s, Lilly became addicted to ketamine and began to believe in a hierarchical group of cosmic entities, the lowest known as the Earth Coincidence Control Office (ECCO). These events helped build the world of Ecco the Dolphin, with producer Ed Annunziata creating an adventure wherein an intelligent dolphin comes into contact with extra terrestrial lifeforms.

The moving background in the dialogue screens of the Mega Drive (and Mega-CD) versions was originally the result of a glitch, kept in because the designers thought it looked cool[19].

The Mega-CD release of Ecco was the first game on the platform to sport a QSound soundtrack[20].

Release

Ecco the Dolphin was the fourth best selling game in the United Kingdom in 1993[21].

Legacy

Ecco was has been re-released for several formats over the years, usually as an emulated Mega Drive game. It was included in Sega Mega Drive Collection for the PlayStation 2 and PlayStation Portable, and was released as a downloadable title through the RealOne Arcade service (also in the form of a one hour trial version). In 2006 it was released on the Wii's Virtual Console service, and in 2007 became a downloadable title through the Xbox Live Arcade service. Ecco was also included in Sega Mega Drive Ultimate Collection. In 2010 it was released on Steam and iOS devices. The iOS version was removed from sale on iTunes in 2015.[22]

In 2013, the game was converted to 3D and released for the Nintendo 3DS as 3D Ecco the Dolphin. It was later included in the compilation Sega 3D Fukkoku Archives.

Ecco the Dolphin was followed by Ecco: The Tides of Time.

Comic adaptation

Sonic the Comic included few "Ecco the Dolphin" comics strips, retelling the general story of the first game in it's own way. The story arcs are: "Ecco the Dolphin" (issue #13 to issue #18) and "Return of Ecco the Dolphin" (#60 to #65).
