For $5, Return to Ostagar is a pretty poor value. BioWare's launch DLC offered important features that you could enjoy throughout the entire game. The Stone Prisoner gives you Shale, arguably the most entertaining companion in the game, as well as a versatile warrior to boot. Warden's Keep gives you an amazingly useful storage chest and access to the best sword in the game. Return to Ostagar has its share of goodies, but nothing nearly as useful or entertaining.
