Okay, this is not a discussion for those that don't want to be spoiled about Dragon Age's changes so I will put a spoiler block on it just to be a nice guy. So here I begin
Okay there are changes to dragon age 2 that some may not know. I will list them so it could be easier to see, some were already leaked/exposed.
1. The Art Style made is becoming somewhat darker.
2. The game seems to be based before, during and maybe after Dragon Age: Origins.
3. The game play will actually be different between PC and consoles
4. DA2 will be based on a single character by the name of Hawke.
5. Voice Over. We know this but what is being done is a ME similar wheel choice. There are no sentences to choose from but more of expression of what you want said. Something similar to Alpha Protocol.
6. Morrigan may make an appearance.
7. The way the story itself is being played out is similar to "The Usual Suspects" Here is a link http://en.wikipedia.org/wiki/The_Usual_Suspects
8. Companions still as talkative and fleshed out as in DA:O. Difference now is that even if they don't like you, they will still stay in your party. You can be hostile to them even. Though if they don't like you they would "...try to show you up."
9. There are now melee combination moves as there were magic combination moves. This also means that magic has finisher endings as well.
So yeah, there is a lot.
