I agree that the Dragonborn race is a must have for me aswell. I've never played D&D or any previous BG games, but research has convinced me enough to suitup with some scales and unleash hell upon the mindfalyers!
The only problem I have is not knowing what class would be best for my playstyle. In DoS2 I play a melee/magic rouge with strength weapon in the left hand, a dagger in the right and medium armor. My gut says that BG3 build mechanics might be more rigid.
For backround I would prefer something similar to the Scholar and mystic tags.
