A Definitive Edition was released a year later on August 31, 2018, which fixed numerous bugs and addressed criticisms of the original release, alongside a release for Xbox One and Playstation 4 (with a Nintendo Switch version releasing a year after that).
It released on September 14, 2017, almost exactly one year after the first act of the game was released to Early Access by the developers.
The game was originally projected for release in December 2016, but having smashed through every single Kickstarter stretch goal with over $2M in pledges, delays were inevitable. Thanks to the success of the original, Larian had enough funds to produce it on their own, but took to Kickstarter once more to attract additional funding, build up a player community early, and to sign Chris Avellone on as a stretch goal. Divinity: Original Sin II is the sequel to Divinity: Original Sin by Larian Studios note although, in terms of the timeline, it actually follows after Divine Divinity and Beyond Divinity, given how the original Original Sin was set over a thousand years before all three.
