April exhibited a "very light release schedule" in terms of "compelling new games." There market is still there for video games, notes analyst Anita Frazier, and these April figures reflect that.
Call of Duty: Modern Warfare 3 came third, followed by Tiger Woods PGA Tour 13 and NBA 2K12. The re-release of The Witcher 2 from CD Projekt for Xbox 360 got it in the chart sixth.
"I think what the new physical retail content sales reflect a very light release schedule in terms of the amount of compelling new games," said NPD's Frazier. "Last April, the top seven titles outsold the top-selling title this year, and, simply stated, there were notably fewer new market introductions."
"I think it's a simple as that because when we see compelling content come into the market, the games are still selling as well as ever - we just saw a lot less this April as compared to last."
She added: "Kid Icarus: Uprising on the 3DS ranked among the top 10 SKU's for the month, and would have made the list if we were reporting on SKU rather than total title level."
