Dunno about graphics and visuals, a matter of taste I suppose. The biggest disadvantage of 3d graphics is how quickly they become dated (there are many examples, I think the best one is the comparison between xneogears and ffviii, two games who came out relatively close to each other) . I think regardless of graphics, Dragon Age Origins brought a great cinematic value to this genre. Something that kinda started with mass effect, but here is shown in a dnd like setting.
