ClayFighter 63⅓ suffered many delays and was released almost a year after it had previously been scheduled. Nintendo Power even ran a cover story and review of the game in the spring of 1997, expecting an imminent release. In the end, the game was released in a fairly rushed state, with several previously-promised features being cut due to time restraints. As a result, Interplay later updated ClayFighter 63⅓ with ClayFighter 63⅓: Sculptor's Cut, which was released as a Blockbuster Video rental exclusive and contains a number of characters that had missed the deadline for the original release. In doing so, they also removed the Killer Instinct-like combo system, and while all the characters from 63⅓ remained, Interplay removed many of the original characters' special and super attacks (presumably due to memory limitations).
