Although you may be sorely disappointed if playing for the story. The Divinity Original Sin 1 was basically garbage in this respect, a poor attempt at doing Discworld, with neither the vision nor talent that Pratchett had.
Original Sin 2 is much better story-wise, though it's still a game where the best story content is in side quests and environmental storytelling. The animal quests are exceptional.
I couldn't believe how many animals have such full dialogue and background. Basically all of them!
