The Mario & Luigi series debuted on the Game Boy Advance in 2003 with Mario & Luigi: Superstar Saga. Praised for its innovative battle system and great humor, Superstar Saga was a resounding success with fans and critics alike. 2005 brought us the sequel, subtitled Partners in Time, which found its home on the DS. Partners in Time was not as well-received as its predecessor. Common complaints included too much linearity and the inclusion of the annoying baby characters.
