- Back to: Sonic R (preview).
General comparisons
The preview has a different title screen, using art that was used fairly extensively in the run-up to release, but was relegated to the end of the credits in the final product. The final game clarifies that 
is a "button". Extra shading was also added to the SONIC text before release.
The menus are in a bare-bones state at this stage. You access different options by pressing buttons on the Saturn controller, as opposed to using the D-Pad to highlight your choice. There is no music on these screens.
The first five characters can be selected, including Dr. Eggman who, in the final, needs to be unlocked.
Only three courses are selectable, and each have generic names. Reactive Factory doesn't even get an icon.
Loading screens are different. In this preview, a crude rotating CD-ROM reflecting the title screen is used, rather than Sonic's head.
Gameplay comparisons
The HUD has not yet been finalised. Character icons are crude and player positions aren't shown on the map.
Characters can't yet collide with each other, meaning the computer will always take the same route without any chance of interference.
The computer also doesn't play by the laws of nature. AI characters frequently intersect floors or hover above ground.
Spinny things don't spin.
The doors that exist require more rings than the final.
Chaos emeralds are a different shape.
