I'm actually on my 17th play through of DA:O I simply love the game it's still facinating an keeps drawing me back, my 2 favorite background story's is the Dalish <getting to see Merrill as a non emotional npc in DA:O to the Merrill in DA:2> Whenever I play a male Hawke, Merrill is his love interest an she is still one of my favorite npc's.
I really enjoy DA:O but I still enjoy DA2 an I can come to accept the generic fact that the area's don't change much as it is a city and not to many city's that I know of change that extensivly over time.
I really hope they take the very best of both games and place them in DA:I an not use the generic Inventory of DA2, everything felt immersive then open the inventory an I felt so totaly pulled away from the game.
Also I kinda would like a demo of DA:I later down the road that actually doesn't have any actual quests from the main game to show off the combat an the story telling.
