Freaky-deaky Tomodachi Collection increased its weekly sales AGAIN and AGAIN. This last holiday-bumped week was its biggest yet.
In its sixth week Dragon Quest IX not only continues outpacing Dragon Quest VIII, but has outsold the initial release altogether! Should take another week or two to additionally outdo what DQ VIII sold in Best form. Though not pictured here, it's worth noting that as of week six Dragon Quest IX is back ahead of Dragon Quest VII: 3.62 M to 3.57 M. Thanks to Chris1964 for keeping up with that stat in particular.
Monster Hunter 3's first week put it ahead of the initial PS2 release of Monster Hunter 2. The second week put it ahead of PS2 MH2 combined with its Best release. The third week is just gravy.
Tales of Versus isn't off to a bad start for a modern Tales game, but it's not quite matching up to this year's first PSP Tales hit, either.
Continuing the comparison of decently successful Puyo games from a few weeks back, it looks like DS's Puyo Puyo 7 is behaving a lot like PS2's Puyo Puyo Fever.
Tingle's second outing doesn't start off as well as his first.
