Asked why fans of the original should replay the Definitive Edition, Larian said that there is more than 30 hours of new content in Act 3 alone.
"The entirety of Act 3 has changed quite dramatically, that's about 30+ hours of content," a Larian spokesperson explains.
"New story moments, particularly for Beast, as well as changes in the narrative arc and the installation of new fights.
"If you've played before, there are so many massive and minor changes that the game will feel fresh in places, and there are many surprises that'll have you going "huh, this is new!" - there are about 8 new fights.
"And our fights are meticulously crafted tactical challenges, not just sort-of mobs placed in the world-map like in some RPGs."
