It's not just the marketing material, the game content and books also suggests a much darker world.
Mages are locked in towers and getting abused and raped
ROA can be called on Mages in worst case circumstances and sometimes have even before the worst happens
Dwarves don't understand the human world, only a few that live on the surface do and even then I don't see them leading anything but Merchant guilds.
People hate and fear the Qunari "oxmen" but use them as mercs
The Qunari want everyone to convert and don't think women should fight
City Elves are kept in the ghetto or they are woodland nomads who kill humans on sight
Nobles can get away with almost anything, including raping city elves at will.
Grey wardens don't give a shyt if you're innocent, they won't save you if you're useless.
The problem with DA (for me) is that while this is presented as how the world is there is a bit too much leeway for the player (hero) to ride in and just change everything. The world sort of bends to the will of the player a bit too much...at least in Origins.
"Sure we'll let you pick the ruler of our country...just because you say so." Yeah right, okay. lol! I only think the options to pick a ruler would have been for Dwarves (Orzamarr) and Couslands (Denerim).
In DA2, the world was more established as the shythole it was and Hawke couldn't change everyone by just walking into the room. Sadly, because players were too used to bending everyone's will they complained about having no power. When really the problem was Bioware not giving us the power to decide what Hawke himself would do. At least, that was my issue with DA2. Having a more neutral path at the end could have helped.
DAI is the absolute worst of them all, they take their entire lore and established world and just toss it upside down and pour bleach on it. Now I'm supposed to believe that an Elf was the first IQ, that a Dalish elf can be the current IQ, Non Mages will bow to mages when even in the books a group of peasants tried to kill them the first chance they got. A dwarf is running around with a magic hand that connects him to the fade even though the game presented Dwarves as unable to wield magic or have a fade connection to the point of not having dreams, humans will now consider a big Qunari Merc as their religious leader?
If anyone think that is the world DA presented to us all along then I have no words.
