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.
Achievements
Main article: Ecco the Dolphin/Achievements .
History
Development
Ecco the Dolphin was inspired by the works of American author and screenwriter Hank Searls [51] (Henry Hunt Searls), particularly by his two novels "Overboard" (originaly published in 1978) and "Sounding" (originaly published in 1982). These two novels 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.
During development the game was known simply as Dolphin [52] .
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.
The Mega-CD release of Ecco was the first game on the platform to sport a QSound soundtrack[54] .
Release
Ecco the Dolphin was the fourth best selling game in the United Kingdom in 1993[55] .
With the launch of Ecco The Dolphin in Europe , Sega France in a colaborative venture[56] [57] [58] [59] with Europe Conservation[60] [61] [62] (European Organization For The Conservation of Natural Resources and Cultural Heritage[63] , a non-governmental organization founded[64] in France, in 1989 by French field Ecologist Jean-Philippe Beau-Douëzy [65] [66] [67] ), the Tethys Research Institute [68] [62] , Sega UK, and Ecofilmes , joined together in a major awareness-raising campaign for the dangers that menace dolphins and other species in danger of extinction[69] .
Sega France donated 5 francs [70] [69] [59] of each of the first 30,000[69] [59] copies of Ecco the Dolphin sold, to the Pelagos Sanctuary for Mediterranean Marine Mammals [68] [71] [56] [57] (a 150.000 francs total), a special marine protected area extending about 90.000 km² in the north-western Mediterranean Sea between Italy, France and the Island of Sardinia, encompassing Corsica and the Archipelago Toscano, which owes[72] its name to a life-size, self-inflatable replica[73] [74] of a blue whale built by a team[75] [76] of engineers in 1989 for the French oceanographer Jacques Cousteau , which was suspended[77] between two cranes, from June 25 to July 7, 1989 in Les Halles , Paris to promote his ocean park Parc Océanique Cousteau (opened in July 1989 by Jacques Cousteau and his son Jean-Michel Cousteau , in Les Halles , as an educational ocean park without living animals, composed only by life-size replicas of marine mammals, the ill-fated attraction closed in November 1992, due to financial problems caused essentially by poor attendance due to the high prices of the tickets and the lack of real marine life). The replica, which was named "Pelagos", was exhibited in France numerous times, over the years, including in 1994 in a suggestive "navigation" on a platform along the Seine river, in Paris. The replica was later donated to Europe Conservation France.
Ecofilmes contributed to the Pelagos project with more 4.000.000$00 escudos and also contributed with 320$00 escudos of each copy sold to help Portuguese environmental organization Quercus - Associação Nacional de Conservação da Natureza (Quercus - National Association for Nature Conservation) in a similar project, in Portugal, called Projecto Delfim[78] [79] - Centro Português de Estudo dos Mamíferos Marinhos (Projecto Delfim - Portuguese Centre for the Study of Marine Mammals[80] [81] , founded in November 1992 by Portuguese Biologists Manuel Eduardo de Noronha Gamito Afonso dos Santos [82] [83] [84] [85] [86] and Francisco Manuel Reiner Ataíde Garcia [85] [86] [87] ) for the study and conservation of the bottlenose dolphins[88] [89] [90] of Sado's River [91] estuary (Setúbal , Portugal).
Ecofilmes promoted a contest[92] exclusive to Clube Sega members, and included numbered coupons[92] , on each copy of the game, which participants, had to fill with their personal details, (adress, Clube Sega [93] member number featured in Clube Sega 's membership card[94] [95] [96] , etc) and mail it back to Clube Sega (the old Ecofilmes headquarters in São João da Madeira , Aveiro, Portugal). Participants with the prized coupon won a trip to France, for three people with all expenses paid to see the dolphins of the Pelagos project.
Sega UK also joined the campaign donating £5000[69] [92] to the Whale and Dolphin Conservation Society [97] [98] , to support the cetaceans conservation program conducted by them in the Moray Firth , near Inverness[97] [99] in Scotland, where a dolphin named Ecco would benefit from the proceeds[97] [99] .
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.[100]
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).
