The week of January 17th – 23rd saw the release of Kingdom Hearts: Birth by Sleep Final Mix
, finally ending the Birth by Sleep chapter of the series. (Then again…) Birth by Sleep Final Mix moved 77,000 copies, taking the place of Another Century’s Episode Portable at #1, above Monster Hunter Portable 3rd at #2. 
Another Century’s Episode, in the mean time, saw itself bumped down all the way to #11 in the span of a single week. Two new Namco Bandai releases in the form of Kaiju Busters Powered and Venus & Braves, along with consistent top-ten regulars like Donkey Kong Country Returns and Pokémon Black/White dominated the first half of the week’s sales chart. Also in the top-ten was Inazuma Eleven 3: Challenge the World – The Ogre, which shot up all the way from #28 to #7. A new shipment, perhaps? Also making its return from beyond the top-20 was Taiko no Tatsujin Wii: Everyone’s Party Sandaime. The top-20 chart for the week is as follows:
