I am not big fan of DnD and didn't play the previous Baldur's Gate but I've followed Larian for nearly 15 years now and it's probably their masterpiece. I love the replayability : For now, I've finished the game 5 times and I always discover a new thing when I launch a new run. Every class is so much fun to play and I love the feeling that the game has thought of everything when you interact with the world or the NPCs. The game has some flaws but it is the closest to perfection IMO. Just enjoy it alone or with friends (or both) !
