Sorta confirming my suspicions that this isn't a real BG game...
I'm not sure what that means though. All the characters and races exist in the DnD universe, and they can't really do the Bhaal spawn plot line and any tie in to it would fall flat because your character was custom made in those titles. I'm not a fan of deep tie ins, always creates continuity and tonal problems, I prefer skin deep contact with prior installment (ie new star wars trilogy vs Mandalorian).
What is it that you mean? Realtime combat with pause? same locations?
