New software groups:
Rhythm Tengoku Gold gets a fast start compared to its predecessor.
Soul Calibur The IVs are the one-week lines that aren't the smallest (which is II Xbox).
Dragon Quest V DS's total remains lower than PS2's, but its third week number is ever so slightly higher. Better legs? They'd have to be significantly better to get far in catching up with the PS2 version's lead, though.
Fatal Frame IV's debut puts it way in the... middle.
