Without a solid historical basis, determining the month's top-selling console might be difficult. So we'll give you a hint: It's been the top selling console for 11 of the past 12 months. That's right, it's the Xbox 360 which managed to move 270,000 units according to Microsoft, representing 39% year-over-year growth and marking the "seventeenth month of year-over-year hardware sales increases," according to a now routine email boast from Redmond.
Overall video game spending is down 13% year-over-year, dropping from $829.4m to $718.8m; while hardware is only down 5%, video game software was down a whopping 19% from May 2010 to 2011. Looking at the list of top sellers, you'll see a few notable facts: the poorly received Brink managed to arrive in second place; there are two Lego games from two separate publishers; and perhaps most notably, there isn't a single Nintendo-published title on the list.
