I would like to point out a couple of problems I had with ED.
The targeting system was sometimes a pain for me. Especially in mob situations, like the flying fortress areas. For instance, trying to take out a nest and suddenly the target automatically switches to an unfortunate dragon killer simply flying by. Or after pausing and trying to aim at a lever or a chest while a mob is attacking you (because I'm so BA I can withstand a mob attack :P), it is annoying to do this.
Also, It would've been cool if there was some more character depth. There does not necessarily have to be any sort of romance angle, but maybe some main character voice acting, cut scenes, or more depth with the interaction with the platforms of the battle tower (as opposed to simple upgrades). As I was playing, I felt like there didn't seem to be any lasting ramification for a gender choice, decision I made, or conversation I had or didn't have.
Now with that being said, I just wanted to say that I did only play the original ED and I don't know if anything was significantly changed in DKS and I don't know if any of these issues have already been raised, so forgive me if they have, I didn't read through all the posts.
Also, I just wanted to say that ED had the best soundtrack I have EVER heard in a game other than LOTR (and that was basically the movies' soundtrack); and I personally think the gameplay is much better than DA:O, I was able to play seamlessly, unlike DA:O, pausing only when I had to target something specific (damn healers!). That is what a true ARPG is.
I have a collection of some of the best RPGs ever on both XBox and PC. I generally resell those that don't live up to my lofty expectations quite quickly. I have to say Divinity 2 will take a place high in my RPG collection.
Great job in making such an awesome game!
