This game is the third role-playing game in the Mario franchise after Super Mario RPG and Paper Mario. Unlike those titles however, Superstar Saga features a lighthearted whimsical script and a greater emphasis on comedy and humor. The player controls Mario and Luigi simultaneously as they traverse the overworld, fight enemies, gain experience points, and find new items and gear. The battle system differs from traditional games of the genre, with more emphasis on timing and elaborate attacks called Action Commands. Created by Shigeru Miyamoto, Tetsuo Mizuno, and Satoru Iwata, the game was announced at E3 2003, later releasing the same year.
