Nintendo has overtaken Sony to become the worldwide leader in video game sales, according to research firm iSuuply.

Combined game sales of the Nintendo Wii and Nintendo DS games totalled $1.2bn during the third quarter of 2007, up 31 percent from the second quarter of this year and more than double the amount sold a year prior.

By comparison, combined PlayStation 3 (PS3), PS2 and PlayStation Portable (PSP) game sales totalled $1bn. Microsoft reached $318m in total Xbox 360 and Xbox 1 games sales.

The news marks the first time that Nintendo has accomplished the feat since being displaced by Sony in the mid nineties when the original went head-to-head with the Nintendo 64.

"Because Sony was slow to reduce the price of the PlayStation 3 and to produce compelling games, third-party game publishers are flocking to other platforms," said iSupply. "If the PlayStation 3 can't promote more game sales, developers may begin to feel working with Nintendo outweighs the benefits of working with Sony."
