EA's latest experiment with mature Wii games doesn't seem to be going so well. According to numbers given to Edge by the NPD, Dead Space Extraction only managed to sell around 9,000 copies in September -- although it should be noted that the game was out for only five days in the NPD's September sales period (September 29 - October 3).

EEDAR's Jesse Divnich, however, cites the sales as the result of a successful not telling anyone about the game experiment. "Electronic Arts didn't market Dead Space Extraction as much as it does with other titles," he told Edge. "And the success or failure of a Wii title usually correlates directly to marketing spend. If Electronic Arts spent little on marketing, I am sure the sell through was no surprise to them." It was, like everything, a complete shock to Dead Space Girl.
