Startling number of Wii Play copies sold

November NPD numbers revealed that, yet again, Wii Play was in the top 10 software sales. The title has consistently placed in the top 10, and so far has sold 7.9 units in total. 15.4 million Wii units have been sold since the system released in 2006. With that in mind, a startling fact is also known about Wii Play – About half of Wii owners have bought the game. Picking up an extra Wii controller with Wii Play is obviously the main purchase incentive here. Standalone controls cost $40, so by adding just $10 to that total, the consumer can pick up a copy of Wii Play along with a Wiimote.
