Do you like the current trend of 5 hour singleplayer FPS games?
Many FPS games have multiplayer as the main selling point - and DA:O doesn't.
Not at all, but this is an add-on. Can't say I've played many add-ons that had "loads" of content. They're not supposed to be on par with full games. Night of the Raven is an exception, but then again, that is the best add-on I've ever played.
How long is Mask of the Betrayer for example? 20 hours? Can't be a whole lot more.
