It has at the beginning choosing his character from Dragon Age: Origins to import or to play a new guard from Orlais. Decisions which are in DA: O hit, although playing an import role, but really they are not decisive. For example, some characters make a brief appearance, but apart from a group member from DA: O you see unfortunately but very little of the old familiar faces. Although you get a new group at its side, but somehow lacks some of you something to come closer to the qualities of the old party members.
From technical point of view there is nothing new to report, the game is based indeed on the same graphics engine as the main game, and differs so neither in the positive as well as negative.
After almost 20 hours I've played through the game now and for the price of 30 euros you get here quite a bit on offer. And I hope that we BioWare further such packages will offer the time to bridge to Dragon Age 2.
