Sonic X-Treme was meant to be a Sonic game released exclusively for the Sega Saturn and Microsoft Windows and was planned to be Sonic's official jump to 3D.
Multiple plots were considered during the game's development.
Why It Was Cancelled
- The prototypes and engines that Sega Technical Institute developed couldn't run properly when tested in an actual Sega Saturn, causing massive amounts of development troubles and delays while trying to make the game work. The Sega Saturn's complicated architecture made the situation even worse for the developers.
- At the time, Sonic's speedy gameplay was very difficult to make work in 3D.
- Yuji Naka refused to let the team use the Nights into Dreams game engine as a starting point to make the game work.
- The excessive amount of work and stress caused the lead developers to become sick and were told that if they didn't quit the project immediately, they would die in about 6 months.
The game was canceled and Sonic 3D Blast was later ported to the Saturn with improved graphics. Some of the elements later made its way into Sonic Lost World.
