During early January to late March 2003 (about a month before the game came out in Japan), a radio show called Final Fantasy Tactics Advance Radio Edition was played across four japanese radio stations. The radio show expanded on some parts of the story as well as various changes in the plot, though still largely the same. Some of these changes includes all the main characters being transported instantly to Ivalice after Mewt reads a spell from the book, a very early introduction to Montblanc's brother (Nono), and a small side story involving Nono's now-named airship (Brilliante).

A dispatch mission called "Scarface" is posted by a Knight with the name Tingel, who wishes to keep a scar from a duel he started. This likely is a reference to the Tengille family from the previous Final Fantasy Tactics game, as all three of the Tengilles were Knights and were also known to use "Tingel" as a surname.

It may also be a reference to Squall Leonhart or Seifer Almasy from Final Fantasy VIII, who both got scars across their face after a duel with each other.

At the beginning of Final Fantasy: Tactics Advance, you encounter three school yard bullies named Guinness, Colin, and Lyle. Later on in the game, there's a mission in which you have to save a professor from three zombies named Guinness, Colin and Lyle.
