EA is act 1 only - it may expand & show us more but its about mechanics & feedback without spoiling the whole story - I think this a good thing - others may disagree but thats all good. Jump into Solaster as well might scratch that itch ??
I really hope they change their stance on that further down the line (AFAWK Acts 2 and 3 are in the storyboard phase right now, the Duergar camp that signals the midway point in Act 1 is not even finished yet), DOS2 suffered from the lack of feedback its later acts got. I read on this forum that the only story element to receive signicant changes in DOS2 due to player feedback was the Red Prince's character. Larian has said that the evil path in Act 1 is being looked at, so here's hoping that that means bigger changes are coming this time.
