What is the best role playing adventure game for the Playstation 3?

Dragon Age: Origins isn't a bad game, good replay value to keep you entertained for a few weeks. Also Fallout 3 is made by the same people as Oblivion and was the 2008 game of the year. Highly recommended if you haven't already played it. Demons Souls maybe aswell but only if your up for a very difficult challenge.
