The Never Finished Games

Ecco for the Sega Genesis 32X?

I've found an article about this unsolved mystery in the internet, so I will paste it here:

"Sega first revealed the existence of this game at the 1994 Summer CES (Diehard Gamefan, Volume 2, No. 9, August 1994) as part of of its official 32X preview for the coming holiday season. The only thing that was shown, according to the lone report that I have, was a Cinepak demo of the game's opening title sequence. This prerendered animation is in fact the source of that mysterious, tantalizing snapshot that haunted Ecco fans throughout the back half of the 1990s. The 32X version of Ecco suffered several problems of an unknown nature during development. As a result, it was pushed back on the release schedule and Kolibri substituted in its place. The game was eventually canned along with the platform. Nobody seems to know what happened to either the 1994 Cinepak demo of the title sequence or to what code remained from the aborted project."

"Based on current evidence, which is admittedly slim, the game itself would have been little more than a 32-bit enhanced version of the Genesis original, including additional (and possibly changed) levels and several prerendered cinemas."

What makes me really wonder is the screenshot itself... Those rendered objects (Ecco, the title) look actually very good, nearly too good. If Ecco for 32X would have had such cinematics, those would have taken a lot space but the 32X cartridges weren't much larger than the Genesis ones... I think the biggest I have is around 4MB...

So the game itself wouldn't have been in 3D, maybe some bonus levels but graphically I don't think it would've been possible to make them look good.
I would rather say that this opening scene has been taken to the Saturn version, since there also has been a game in production. Due to such high quality which the 32X probably couldn't have handled it, but since the Saturn project has also been cancelled we will probably never know...
