Option 1. If they had the licence it would probably be called BG3.
It's better than BG2 because of the characters IMO. They're deeper, more fleshed out, more believable because they have more lines of dialogue, plus the benefits that 3D and animation bring to visual character. And, er, I confess I found most of the BG1/2 cast to be annoying. Gameplay is very similar.
Dragon age also benefits from not having AD&D character creation. I hate those rules! Both overly complex and overly simplistic, hard for a dyslexic to make sense of and so limiting I can't make a character I like. 3rd edition rules were a lot, lot better but the infinity engine games didn't use them.
