The new kid on the Japanese Wii software block last week was Battalion Wars 2, which faired well enough in its debut to hit the top ten. Will it stay there? Our guess is no, sadly. Still, it's nice to see the game get some recognition in Japan.Once again, the only non-Nintendo title for the Wii that made the top thirty was Deca Sports, which dropped thirteen spots from the week before. Ouch. We're not sure what made Japan fall so out of love with Deca Sports in one week, but the game seems to have lost some of its legs. Smash Bros. Brawl also took a spill, falling from tenth place to nineteenth.
The other noticeable drop was Mario Kart Wii, which only fell one spot, but an important spot -- from first to second -- and finally succumbed to the frightening power of Monster Hunter Portable 2nd G. Hardware was also a PSP victory, as the handheld beat all other systems by a convincing margin.
Now that you've seen the hardware numbers, check past the break for the software sales.
