Guitar Hero: Warriors of Rock sold only 86,000 units in the US in its first week according to analysts Cowen & Company.
The figures indicate a dramatic decline in sales for the series. The previous instalment released last year, Guitar Hero 5, sold 499,000 copies in the US its first week. 2008’s Guitar Hero: World Tour topped 500,000 in its first week. 2007’s Guitar Hero III sold more than 1.4 million units in its first week.
The opinion of many analysts and specialist media commentators has been that the rhythm genre has peaked. These figures may corroborate that sentiment.
