For the fifth month in a row, the PlayStation 4 was the top selling system in North America, according to market research company NPD Group’s May report. Sony’s new home console has bested Microsoft’s Xbox One in sales since their launches this past November, with the PS4 selling 7 million (as of March 31) compared to Xbox One’s 3 million (As of March 31).

Nintendo’s 3DS placed second overall, and the Big N enjoyed an increase in sales of 90% over last May for the Wii U. This is certainly good news for Nintendo coming out of E3 and doubling down on development of Wii U games. They can thank last month’s release of Mario Kart 8 for a significant boost, as the game sold 1.2 million copies in its first week in stores.

The PlayStation Vita also received an unexpected boost in sales with a new redesign of the Sony handheld bundled with a port of 2K Games’ Borderlands 2. The Vita has been almost an afterthought in Sony’s marketing, save for streaming PS4 games to the device, so it is a bit surprising to see that the NPD reports an increase in sales for the system.

The top selling game of May was Ubisoft’s Watch Dogs with over 4 million copies sold worldwide. A game that certainly had plenty of hype coming in, Watch Dogs didn’t exactly reach the loft heights it promised, but a foundation for future installments has been made due to topping the sales charts this month.

The rest of the top ten selling games for May include MLB 14: The Show, Wolfenstein: The New Order, Minecraft, The Amazing Spider-Man 2, NBA 2K14, Titanfall, Kirby: Triple Deluxe and Call of Duty: Ghosts.
