On October 4, 1999, Sega announced that a sequel to "Sonic Adventure" was in development. "Sonic Adventure 2" made its debut at E3 2000 and was released in June 2001. The sequel was designed to be more action-oriented than the slower-paced, story-centric "Adventure" and to give all the characters equal playtime. Like its predecessor, "Sonic Adventure 2" received positive reviews. A concept for "Sonic Adventure 3" was reworked into the 2008 game "Sonic Unleashed". In 2017, Iizuka stated there were no plans for a third "Sonic Adventure" game, saying it would not advance the series' design. He did not rule out the idea, saying "If we can get the gameplay to evolve and get to a place where "Adventure 3" makes sense, then you might see an "Adventure 3" come out". In December 2018, Iizuka expressed interest in remaking "Sonic Adventure".
