An anonymous reader writes "In terms of console usage, the aging PS2 still leads the competition, according to data from US research firm Nielsen. Data the company compiled between January and October 2008 shows that the PS2 commanded 31.7 percent of the total number of minutes spent playing consoles. Only 37.9 percent of play time took place on current-gen systems, with the Xbox 360 (17.2 percent) leading the Wii (13.4 percent) and the PS3 (7.3 percent). Users even spent more time playing on the original Xbox (9.7 percent) than the PS3, while Nintendo's GameCube (4.6 percent) wasn't far behind Sony's new console either." World of Warcraft once again topped the most-played PC game list by a large margin. Tetris was the top mobile game, followed by Bejeweled and Guitar Hero III.
