Dos2 DE is a variable I didn't consider at all in all of my comparisons... What are the biggest differences between normal dos2 and de?
Added some minor quest and story content.
Can you elaborate about this part a little?
They added Ser Lora as a companion for the entire game, who is a Squirrel Knight. He follows you around and occasionally says stuff.
Some of the end-game quests and content in Arx were expanded upon and given some additional combat to make the story flow smoother. IMHO, it was just more stuff to kill for EXP and it didn't really tie the story together.
And now they added some sets of armour and other items that have its own story, but I haven't played it since they added this.
