29/40 is a terrible score for a Japanese high-profile game in Famitsu.
The only conclusion I can draw is that it's flawed, or just plain stinks, like Last Remnat.
BTW, what score got Lost Odessey, Last Remnat, Tales ov Vesperia, Infinite Undiscovery from Famitsu?
I believe White Knigthe Cronicles will have trouble to even reach 500,000 copies. 550,000 copies tops.
