Ecco the Dolphin had been a huge success for Sega and Novotrade, but both it and its sequel are often regarded as very challenging and often confusing video games meaning they are unsuitable for the young market. Despite this, Ecco was bought with young children in mind, which prompted the creation of Ecco Jr. which would attempt to appeal to a younger audience with the extreme difficulty removed. Unlike other games in the series, it is impossible for Ecco (or his friends) to die, and the focus is placed on completing simple tasks and on educational material about dolphins.
Despite the lack of gameplay value for older gamers, Ecco Jr. has been re-released as part of the PlayStation 2/PlayStation Portable title Sega Mega Drive Collection (where it saw its first European release). It was also released as part of the Wii's Virtual Console service (where it saw its first Japanese release).
