1) Good length. I don't mean DA:O style. Origins only had a few main missions but those missions were really long. For DA3, i'd like to see shorter missions but a lot more of them and a lot of side quests. So if people want to blitz through the main story, they should be able to, but for people like me that love optional side quests, we should be able to have plenty of those too. The longer the game the better I think.
2) Customization. By this I mean not just the character creator but the whole game experience. I don't mind if my party wear pre-set clothes but I would still like to give them stat boosting equipment even if I can't see it. Just as long as my main character can change appearance though.
3) More towns. One of the things I loved most about Origins was being able to travel to different towns and see the different shops there. DA2 was a fun game but only really having Kirkwall and the elf village was a bit samey.
4) Better love interests. I loved the all-bi of DA2 as it meant I had the choice of 2 female characters rather than just 1 as I did in Origins. However I think Mass Effect 3 did romances better than DA2. Have some straight, some bi and some gay. Maybe 1 per gender? That way, the romances are unique and not just the same thing whether you play as male or female. It worked well with Mass Effect - showed video games are moving forward in a positive way!
5) A good CE! The game isn't out for a long time, that's long enough to ask us what we want to see in a special release. A lot of us would pay good money for a good limited edition release with some physical items in. Just please if you do this, give the UK what the USA gets. Don't make a good CE then limit it to one country.
So excited!!
