Excellent writing, original worldbuilding, memorable companions, meaningful choices, and fun mechanics make this a true classic. If you've ever felt that evil parties got a watered-down campaign in other CRPGs, you'll appreciate that evil playthroughs are catered to. Lastly, I really like having a home base in RPGs, like the camp in BG3 or the boat in Original Sin 2, and this has that as well.
