I have never missed the free roam. I actually don't like free roaming since it's just a time sink most of the time and it takes time away from the designers to actually design interesting content instead of a waste but generally empty area for you to travel through.
But what I REALLY miss is good optional side story/areas.
The game is setup so you start of with your Origin story of choice > Ostagar > Lothering > Main quest/World Map > Landsmeet > Final Battle.
But problem I'm having is that there's only really 5 points of interest on the world map and they are all part of the main story. When you look back on say Baldurs Gate 2 you had a ton of great optional content. I'd go so far to say around 60% of the totalt playable contant was optional.
I know it takes a lot longer to develop something today in hi fidelity 3D compared to the pre rendered 2D art in BG2. but I still wish they would have focused more on having great areas to explore, bosses to fight and less on political choices.
But hopefully Dragon Age will be like the Baldurs Gate series. BG1 was a great game, but BG2 was a legandary game. They already have a great engine in Dragon Age so hopefully they will be able to just push out great content for the sequel.
Also... BRING BACK 6 MAN PARTYS! Pretty please with suger on top
