I just picked it up last night and briefly played it. The graphics seem to have unfortunately taken a step down from Dawn of Sorrow. I enjoy the system of switching characters on the fly, and using the two-character function to solve the puzzles. A lot of the reviews say that the castle design is bland and unoriginal, which I could see happening as the castle entrance didn't seem to really be anything special.
And the totally sweet preorder box is going for around $60 on eBay. o_o
