If all they improve from DA2 is add a bit more free exploration, a lot more side quests and have your choices result in more impact on the ending, I would be pleased.

(I'm referring to quests where you actually need to speak with an NPC first, rather than simply finding something in a chest and then getting gold from a random stranger.)

It would also be nice to see a more complex implementation of joinable factions and a crafting system that is actually fun and worthwhile, but I'm not going to hold my breath for either of those to happen.
