BD seems more linear to me, at least as far as ive played (beginning of act 2). More story driven events - SPOILER - I liked it when I was suddenly teleported to another world by a necromancer (though i dont know who he is despite my character saying they've met before....??) - END SPOILER - although I think the interface needs some fixing up, it would be much better to have one character follow the other around rather than selecting both of them. Plus it's buggy. I'd also like some music variation, I've heard the same few tracks a lot of times.....
