Even though the game has an "E for Everyone" rating, it still has a "Mild Lyrics" warning. This is because both of the songs "Deeper" (theme of Death Chamber) and "Kick the Rock" (theme of Wild Canyon) use the word "damn". Additionally, "Kick the Rock" refers to the character Rouge as "sexy and smooth" followed by an innuendo referencing "jewels" in the next line. The parts in which both songs use the word "damn" are cut out of the loops found in the game, and can only be heard in the soundtrack versions.

The Dreamcast version doesn't contain the warning, as the Mild Lyrics warning was added to the Gamecube version, and is in the rating for every subsequent release.
