Its a good job Dragon Quest Monsters is doing such a good job on the DS, otherwise the games charts in Japan would look rather lop-sided. In a rather quiet week for sales, as most of Japan is on holiday, the other four spots in the top five are all PSP games.
1. Dragon Quest Monsters (NDS) 43,886 sales
2. Patapon 3 (PSP) 21,546
3. Pro Baseball Spirits 2011 (PSP) 20,090
4. Final Promise Story (PSP) 18,185
5. 2nd Super Robot Wars (PSP) 13,670
You can see the full chart over at Andriasang, with three other PSP games in the top 20.
