But the biggest culprit to the decline is apparently games like Halo 3 and Call of Duty--those with high replay value. Gamers are purchasing these titles and spending most of their time playing the multiplayer portions rather than going out and buying new games.
"We estimate that a total of 12 million consumers are playing Call of Duty Modern Warfare 2 for an average of 10 hours per week on the two platforms' respective networks, and the continued enjoyment of this game (along with an estimated 6 million Halo online players, 3 million EA Sports players, and 5 million players playing other games, such as Battlefield, Red Dead Redemption, Left 4 Dead and Grand Theft Auto) has sucked the available time away from what otherwise would be spent playing newly purchased games," he said.
