Aside from the anime, two manga sequels were released in Dengeki Hobby Magazine.
Unlike other Gundam titles, Gunpla Builders Beginning G takes place in a present-day timeline.
The three episodes were later compiled and released on both DVD and Blu-ray on December 22, 2010. Both versions include a 16-page liner note. The Blu-ray Collector's Edition includes an original CD featuring its theme "my Proud, my Play!", a sound drama, plus an original slipcase and special features such as audio commentary, music videos and Gunpla TV ads.
Made to celebrate the 30th anniversary of the Gundam plastic model kits.
