Sonic 3D Blast was the final
Sonic the Hedgehog game produced for the
16-bit Sega Genesis, and was developed as a
swan song for the system. The basic concept was conceived by members of
Sonic Team during the development of
Sonic the Hedgehog 3 (1994), but most of the programming was done by the British studio
Traveller's Tales because Sonic Team was developing
Nights into Dreams (1996) at the time. According to founder
Jon Burton, Traveller's Tales had just finished developing a
Toy Story game and wanted to start developing games for
32-bit systems such as the
Saturn and
PlayStation. In retrospect, Burton stated that he believed the game was commissioned because
Sonic X-treme, in development for the Saturn at the time, was struggling, and Sega wanted to bring Sonic into the
3D era of gaming. It was originally titled
Sonic Spindrift. Burton, who served as lead programmer, implemented an
exception handler where, should an error occur, the game would greet the player with a secret level select screen instead of
crashing; this was done so the game could easily pass Sega's approval process for publishing games. Burton also gave the game a unique
full motion video intro sequence, and used compression methods to make the video fit in the 4
MB cartridge and appear higher resolution. The game makes use of some pre-rendered
3D models converted into
sprites. Inspiration for the isometric viewpoint was drawn from
Sonic Labyrinth (1995) and
Super Mario RPG (1996). The item collection was influenced by the 1984
Flicky game, and the graphics were inspired by
Donkey Kong Country (1994). The game was ported in seven weeks, during development of the Sega Genesis version. While it does feature graphical changes, such as weather effects and higher resolution textures, the game largely plays the same as the original version. It features a higher quality opening video and improved graphics. Sonic Team filled in for development of the special stage in the Saturn version of the game, which includes
polygonal graphics as opposed to sprites only. The soundtrack for the Genesis version, which features 24 tracks in total, The Saturn version features a different soundtrack in
CD audio by
Richard Jacques and features a vocal ending theme titled "You're My Hero", performed by Debbie Morris. The musical styles on the soundtrack were described by
Sega Saturn Magazine as both traditional
Sonic music and "
hardcore techno". ==Release==
