Game Development:Sonic 3D: Flickies' Island

From Sonic Retro

Sonic 3D: Flickies' Island had gone through several changes over its development process. There are several rejected ideas, level designs, and other things that were left on the cutting room floor. The following details several of these things.

Development Process

In addition to the original Sega Genesis version, Sonic 3D was also developed for the Sega Saturn to make up for the cancellation of Sonic X-treme. The game was ported in seven weeks, during development of the Mega Drive version. A minigame called Sonic Pool was considered for inclusion in this version but was scrapped.


Many prototypes of Sonic 3D have been found over the years. The first to be found was this 2006 cartridge prototype. Then in 2008 drx released 7 more Mega Drive protos: beta 73, beta 814, beta 819, beta 825, beta 830, beta 831, and beta 94. The 825 beta is quite similar to the 2006 cartridge prototype. At this same time a Saturn tech demo was also found.
