Due to the cancellation of "Sonic X-treme", the Saturn lacks an exclusive "Sonic the Hedgehog" platformer; instead it received a graphically enhanced port of the Genesis game "Sonic 3D Blast", the compilation "Sonic Jam", and a racing game, "Sonic R". The platformer "Bug!" received attention for its eponymous main character being a potential mascot for the Saturn, but it failed to catch on as the "Sonic" series had. Considered one of the most important Saturn releases, Sonic Team developed "Nights into Dreams", a score attack game that attempted to simulate both the joy of flying and the fleeting sensation of dreams. The gameplay of "Nights" involves steering the imp-like androgynous protagonist, Nights, as it flies on a mostly 2D plane across surreal stages broken into four segments each. The levels repeat for as long as an in-game time limit allows, while flying over or looping around various objects in rapid succession earns additional points. Although it lacked the fully 3D environments of Nintendo's "Super Mario 64", "Nights"' emphasis on unfettered movement and graceful acrobatic techniques showcased the intuitive potential of analog control. Sonic Team's "Burning Rangers", a fully 3D action-adventure game involving a team of outer-space firefighters, garnered praise for its transparency effects and distinctive art direction, but was released in limited quantities late in the Saturn's lifespan and criticized for its short length.
