He notes it depends on "how you play games," either rushing through or taking your time. It's longer when side questing, with full bosses "tucked away".
“Take a look at how you play games,” said Laidlaw. “I’d say it’s a bit longer than Mass Effect but shorter than Origins.” The original Dragon Age could take 30 to 100 hours. Dragon Age II is not as 'open' as Origins with the majority of story happening in Kirkwall.
"The game will take longer with side quests,” he continued, teasing that there are full boss creature fights awaiting those willingly to dig deeper. "At the same time, you can get through the story quite a bit faster because so much content is off to the side. Mileage will always very, just take your habits and extrapolate.”
The sequel is a more "aerodynamic" than its predecessor, making it more accessible but avoids becoming some "streamlined experience.” It has complexity but isn't overbearing: “You won’t have to spend a year in character creation,” he commented.
Dragon Age II releases on Xbox 360, PS3 and PC in US March 8th, EU the 11th.
