Let me start off by saying I’m having a blast playing this game. I’ve Played BG 1 & 2 for like 20 years regularly, and was always intrigued by the Forgotten Realms.
So about four years ago, I’ve bought a bundle off the first 30 books about Drizzt Do’Urden, a Drow Ranger, by R. A. Salvatore. If you did not know about these books, I’d like to recommend them wholeheartedly to you, if you love the world of BG3. The books are true to the material, and offer deep insights into Faerûn.
They have their ups and downs, but I’ve read 14 books so far, and I’ve been deeply involved so far.
I’m surprised he isn’t in the game himself. They put everyone else in; from BG1 and 2, to actual legends like Elminster.
