Nintendo sold as many Wii games consoles in February as both its main competitors put together, according to figures released in the US. 

Research firm NPD put the Nintendo Wii at 355,000 units for the month. Microsoft's Xbox 360 managed 228,000 units and Sony's PlayStation 3 just 127,000. 

Microsoft has now sold 5.1 million Xbox 360s, while Nintendo and Sony are still yet to ship two million of their latest machines. 

"If the Xbox 360 and the games that work on it continue to gain share, Sony is in real trouble," said Douglas McIntyre, an analyst at 24/7 Wall Street. 

"The Wii caters to a different, lower price point in the market, and should continue to roll up big numbers. Not so the PlayStation 3."
