"GTA IV captured two of the three top game spots, realizing an attach rate of 20% to the combined Xbox 360 and PS3 install bases," said Frazier. "With only five days at retail during the reporting month, GTA IV is one of the fastest-selling titles in video games history"
Nintendo's Mario Kart game came in second at 1.12 million copies. The company also grabbed the fourth and fifth spots for its titles Wii Play and Super Smash Bros. Brawl. The company's Mystery Dungeon games for the handheld console Nintendo DS also did well and ranked seventh and eighth. Activision was the only other independent publisher to find a place on the top ten chart with its Guitar Hero III title for the Wii (152,000 copies sold during April) and Call of Duty 4 (141,000 copies) for the Xbox 360. Overall sales of games software was up 68% to $654.7 million. Hardware sales rose 26% to $426.2 million last month.
