The Divinity games that I tried were: Divinity Original Sin, which I couldn't play because it felt like it was a co-op game and playing in single player.... I felt like I was talking to myself, and competing against myself for dialogue rolls, haha...
Divinity Original Sin 2 however! That was so much fun and indepth and felt like a proper experience, I loved it.
Will have to watch this guy's youtube and get the BG story!!
His vids are really well made ,I've studied video editing for a long time and found myself thinking damn son you put in the hours on these things!
There not super long both under 20 mins I believe.
The Descent into Avernus Dungeons and Dragons campaign has highly influenced the BG3 storyline, making pacts with Devils and the like is a pretty cool theme.
