Square Enix’s Dragon Quest IX was the bestselling game across Japan, the US and the UK during the third quarter of the year, according to sales trackers the NPD Group, GfK Chart-Track and Enterbrain.

Despite only being released in Japan, Dragon Quest IX outsold its nearest rival by almost one million units between July and September.

The top five sellers for the period were as follows:

Dragon Quest IX (Square Enix) - 3,925,000
Wii Sports Resort (Nintendo) - 3,014,000
Madden NFL 10 (EA) - 2,612,000

Halo 3: ODST - 1,847,000

The data comes from the latest Top Global Markets report, which also showed a strong rise in Japanese software sales during the third quarter, but a decline in US and UK sales during the period.
