In 1999, Sunrise launched the Gundam Big Bang Project to celebrate the 20th anniversary of the franchise. It involved several productions, but the two most notable were Turn “A” Gundam and G-Saviour. You can say they’re fruits from the same tree that fell on completely different paths. The former, while initially polarizing, is now considered one of the best entries in the franchise. The latter is a forgettable mess that 20 years after its release, it’s still being debated on whether people at Sunrise (or now Bandai-Namco Filmworks) and Bandai-Namco itself recognize its existence.
