About

Mario's Mission Earth was a cancelled third installment of the SNES educational games that would've followed a similar formula to Mario is Missing! and Mario's Time Machine, with the main focus being set on the solar system. Nothing is known about the project apart from a mention on the resume of Mark Knight, the composer for the SNES versions of Mario is Missing! and Mario's Time Machine.
