Still, there's one surprise tucked away in there: Interplay's recent "Fallout Trilogy" bundle--packing Fallout, Fallout 2, Fallout Tactics--popped up as #7 on NPD's chart.

As usual, digital distribution outlet Direct2Drive saw some significant changes to its best-sellers over last week, mostly thanks to a recent sale on Ubisoft-published titles.
