I've only level 12, I've started over about 5 x before finding the class I really liked. But wow... theres so much to do in this game its almost overwhelming. I don't even have time to read all the lore theres so much of it. The other night I sat there reading the codex for close to an hour and a half.
If you didn't like the previous Dragon Ages where you have a nice environment with a narrow corridor that you had to follow... you won't find it here. Massive and beautiful maps with a plethora of quests, variety of enemies and dragons, gear to find and create.
I really liked how they built on a previous DLC story to (Legacy) to build the villain, and include previous games in the story. I just did a mission last night that had me helping Hawke from DA2.
Anyways I have to go play some more DAI, lots to do lil time.
