This year's August NPD sales numbers were, as usual, dominated by EA's monolithic Madden franchise -- but who's that creeping out of the shadows? "I'm Batman."

Rocksteady, Warner Bros. and Eidos officially have themselves a critical and commercial hit in Batman: Arkham Asylum, with the game having sold more than half a million copies across PS3 and 360 in its first week on sale. Even the Joker can't laugh at sales like that.

Hardware saw a slight increase for the month, with the exception of PS3, which saw an impressive 72% jump in sales, no doubt due to early sales of the lower-priced 120GB slim SKU. Wii is still the best-selling home console, but its numbers are gradually dipping down into "maybe we should consider a price cut, too" territory. Here's how sales of the stuff we play are games on stacked up:

-DS: 553K14K (+2%)
-Wii: 277K24K (+9%)
-360: 215K12K (+6%)
-PS3: 210K88K (+72%)
-PSP: 140K17K (+13%)
-PS2: 106K2K (-2%
