"The 106 percent increase in hardware sales was lifted entirely by console hardware sales, which were up by over 200 percent," notes NPD analyst Liam Callahan. Sony claims the PlayStation 4 was yet again the highest-selling console (for the sixth consecutive month), and Microsoft says that the Kinect-less Xbox One doubled its sales in June. Nintendo's Wii U has experienced a 48 percent growth in hardware sales for the first half of 2014, a feat the company attributes primarily to the success of Mario Kart 8. Despite a decline in overall portable console sales, the 3DS saw a 55 percent increase in sales over May, according to Nintendo.
Though Mario Kart 8 has been very successful, it did not take the top software sales spot for June.
