NPD Group's monthly report of U.S. physical video game sales showed a double-digit decline in dollar sales for last month -- a drop that could've been much worse if it weren't for a couple high-profile titles. Irrational Games' BioShock Infinite topped Crystal Dynamics' Tomb Raider on the sales chart, but both drove overall industry revenues to $992.5 million for the five-week retail month of March. That's a 10 percent decline from March 2012 (a little easier to stomach than February's 25 percent decline). NPD's Liam Callahan said BioShock Infinite and Tomb Raider's launches had "the highest first month sales for games in these franchises." March's results show how the box-centric game publishers have been relying on fewer, bigger titles. Callahan added, "There were actually fewer new launches -- about 20 percent less new games -- than last March, but March 2013 launches generated close to 70 percent more dollar sales per SKU than last year."

3DS sales rise

For another month, video game hardware was the segment hit hardest, generating $221.6 million for the month, a 32 percent decline. Portable consoles drove the dollar sales declines, but home consoles also slipped. Nintendo 3DS sales bucked that trend in March, however, with hardware sales that grew 9 percent compared to the prior year. For a seven-and-a-half year old console with a successor on the horizon, Xbox 360 sales were relatively healthy at 261,000 units during the month. While Microsoft boasted about its top-selling console in a press statement, both Sony and Nintendo have kept quiet about the NPD figures for their flagship home consoles, PlayStation 3 and Wii U.
