Demo Rewards, and 'extras'
Download the demo? Make sure you run through it start to end, then, as EA has said (http://dragonage.bioware.com/da2/demo?sourceid=eag2960&om_u=227211 3436&om_i=_BNZG4HB8ZSVO3A) there's going to be at least one guaranteed reward for doing so. Hayder's Razor, an ancient blade with health, mana, and combat ability increases is yours in the full game, if you complete the demo.
Additionally, if the demo sees 1 million downloads before March 1, they're going to unlock two more items for everyone. The Far Cliffs of Kirkwall and Lothering's Lament give money and XP respectively, when read.
More info on both at http://dragonage.bioware.com/da2/demo?sourceid=eag2960&om_u=227211 3436&om_i=_BNZG4HB8ZSVO3A
If you haven't downloaded and played this demo, you owe it to yourself to do so. It's really worthwhile and enjoyable!!!
