Ecco the Dolphin was developed by the Hungarian studio Novotrade International and published by Sega for the Mega Drive/Genesis in December 1992. Designer Ed Annunziata drew on Hank Searls' novel Sounding, which deals with echolocation, and made the game hard on purpose so renters could not finish it over a weekend. The hero was first called Delphinus; Clyde Grossman suggested "Echo", which became "Ecco", roughly "I see" in Italian.
The level "Welcome to the Machine" takes its name from a Pink Floyd song, and Annunziata played Pink Floyd to the music team to set the mood. The Sega CD version added a CD soundtrack by Spencer Nilsen, and the 8-bit Game Gear and Master System versions have their own levels.
The Japanese Mega Drive release came out on 30 July 1993 and is easier, with bug fixes and two extra levels. The Mega Drive version sold over 570,000 copies worldwide.1

The Japanese version adds two levels, Open Ocean 2 and The Stomach (reached when the Vortex Queen swallows Ecco), three save glyphs in Welcome to the Machine and three exclusive music tracks.3

Best version
The Japanese Mega Drive release from 1993 is the most polished cartridge version: it fixes bugs, adds checkpoint glyphs and two extra levels, and is less punishing. The 3DS 3D Classics edition lets players pick it.3

The Mega Drive version was a bestseller, with over 570,000 copies sold worldwide. Reviews were favorable (Mean Machines Sega 97/100, EGM 33/40, a MegaTech Hyper Game award), and Mega ranked it 24th among Mega Drive games.1
