This was the final Sonic the Hedgehog game to have the original voice actors. Afterwards, every Sonic game from Shadow the Hedgehog (2005) up to Sonic & Sega All-Stars Racing (2010) used the voice actors from the English Dub of the Anime series Sonic X (2003).
This is the last Sonic game before Ryan Drummond and everybody else is replaced with actors from 4Kids! Entertainment. Sonic and Shadow by Jason Griffith, Tails by Amy Palant, Knuckles and Vector by Dan Green, Amy by Lisa Ortiz, Dr. Eggman by Mike Pollock, and more. Many Sonic fans criticized this change, but eventually got used to the new voices in the form of Sonic X, the anime from 2003 that ran until 2006.
Sonic Advance 3 is the last Sonic game where the voice of Tails is provided by a child actor (William Corkery). Tails was voiced by child actors from 1998 to 2004. Actresses haven since taken over the role.
