wow long list...
1) I'd like to learn more about the rest of Thedas, Orla, Weisshaupt, Antiva etc... all these exotic lands we here about that I want to see.
2) learn more about the Qunari, perhaps go to Seheron or Par Vollen to learn more about our horned neighbors (who look suspiciously like Flemeth in DA2). Personally I would have liked to have a huge horned Qunari on my team.
3) learn more about the dwarves, about Kal Sharok and the dwarves there, how they live and through them learn mre about the lost theighs, especailly the lost one we found in DA2, very interesting.
4) learn about the elves, perhaps the Dalish will consider building another nation and we be apart of it, or find the original Arlathan, sounds interesting
5) Learn more about the origins of the Darkspwan, something tells me we don't know the whole picture. or what we think is true is actually a lie, also follow up on the awakened darkspwn.
6)who or what the hell is Flemeth, something tells me that turning to a dragon is not the worst thing she can do...
7) follow up on our friends from all the games, even awakening. Even let some of them join our party during the game.
8) The templar mage war, an event this big must have a terrible war to follow
9) Grey Wardens, can't have a game of Dragon Age without them, and what becomes of our Grey Warden from origins
10) New worlds, places and creatures we haven't heard of or seen.
11) Choices, we want our choices in previous games to matter, I don't care if it adds years to the development I'll wait.
12) As for technical and graphic issues, the gameplay was nice in DA2, fast paced fighting was nice but a bit too fast, slow it down a bit so we can have fun stabbing or shooting fireballs, also the graphics in DA2 feels a little rushed, faces look less real then origins and the colors were so strong, I'm not an expert but that's how I feel.
I know it's a very long list and you probably won't get all of it, though I'm hoping they'll be more dragon age games after the third then maybe you'll get it all, but I trust you'll get most of it. I always loved Bioware's games, even though lately some of the games fill a little rushed I still think theyre great
