Terranigma Trivia (SNES)
Hidden roomThere's a hidden room accessible by entering a trashcan located in the empty lot of Neo Tokyo, after defeating an enemy you'll be transported to an office where you can chat with a group of chickens hard at work programming. These fellows are actually Quintet, and they even explain that they are working on Illusion of Gaia 2 !
TitleThe literal translation of the title Tenchisôzô into English is something along the lines of "Creation of Heaven and Earth". Which is exactly the content that the game deals with.
ReleasesAlthough both of the other Gaia games were released in North America, for unknown reasons, Terranigma was not, even though an English translation was done for its UK release.
