Ecco II: Sentinels of the Universe
Sega Dreamcast · 2001
About this game
Ecco 2: Sentinels of the Universe was 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.
Given the fact that the first game was later ported to the Sony Playstation 2 later the same year, it’s not clear why Appaloosa Interactive decided to stop development on the sequel, rather than port it to PlayStation 2 as they did with the first game.

The game was uncovered to the public in 2016 by Hidden Palace, a wiki community dedicated to video game development preservation.
This build comes from a Katana Dreamcast development kit.
The discs were included along with the kit.
The game features "a few playable level via level select with a complete working debug mode," but there is no music or sound in them.
About Sega Dreamcast
Sega's final console, the Dreamcast (1998/1999), was ahead of its time with built-in internet connectivity and an influential library, but a short commercial lifespan cut its game catalog short. That abrupt end means Dreamcast print runs were smaller across the board than a longer-lived console would have had, and it's now one of the more actively collected fifth/sixth-generation systems specifically because of that scarcity.
Gamevaro tracks Ecco II: Sentinels of the Universe for Sega Dreamcast with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Ecco II: Sentinels of the Universe to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This DC release dates back to 2001.
