Dreamcast Ecco lot
In 2008, some items from the development of various Ecco the Dolphin projects during the time of the Sega Dreamcast appeared on eBay. The lot included various prototype builds, source code, and development asset backups mostly of "Ecco the Dolphin: Defender of the Universe", but also included material for the canceled sequel "Ecco II: Sentinels of the Universe". The lot was purchased by Drx and was archived and released in pieces starting in June of 2016, along with other Ecco the Dolphin development material from various sources, for "Ecco Month".
Ecco II: Sentinels of the Universe (Sega Dreamcast)
A planned sequel to Ecco the Dolphin: Defender of the Future for Dreamcast that got canceled around the time SEGA announced that they would be stopping production on the console and focus on being a third-party developer.
