The folks over at GreyWardens.com let us know that they've put together a brief review of Return to Ostagar, now that the Dragon Age: Origins addon is officially available for download. The final score is 7 out of 10 "darkspawn emissaries":
Return to Ostagar is not a terrible DLC, but it could have been better. The lore supplied is interesting and hints at things to come. The battles are fun and for the most part challenging. Even the loot is varied, supplying a Warden with a nice new selection of Darkspawn killing tools.
