I really do like Castlevania: Lord of Shadows; one of my favorite games this gen
in Story, Would give it to LoS, the ending was just heart-wrenching, and the real ending blew my mind.
everything else would go the GoW III; combat was much more fluid, the scale was enormous(from start to end), and the graphics are some the on any console.(the CS:LoS was a visual treat as well)
