A Final Fantasy game doing well? Who would've thunk it?! Square Enix's PSP-only Final Fantasy brawler has continued its dominance over the Japanese game charts in January, with over 186k units sold in January. This bumps the total number of copies sold to 846k. It's clear that it will only take a few more months for the game to cross the million threshold.
The rest of the top 10 charts are dominated mostly by Nintendo games, with the odd exception of Monster Hunter Portable 2nd G (yes, they're still buying that game), and White Knight Chronicles for PS3. See the full list at IGN.
