EEDAR analyst Jesse Divnich shared findings with Industry Gamers highlighting stable sales for mature games despite broad declines for other categories. Divnich told the news outlet that the findings show how core gamers represent a stable market with some resilience to the industry’s booms and bust cycles. EEDAR data shows sales of games classified as mature remained flat in 2009, combining titles rated M by ESRB in North America with those rated 16+ or higher by PEGI in Europe. The category was driven by high profile shooters such as Activision’s Modern Warfare 2, Microsoft’s Halo 3: ODST and Take-Two’s Borderlands. In comparison, all other ESRB and PEGI rated titles saw double digit declines for the year. The biggest decline was for teen games rated T by ESRB or 12+ by PEGI. Divnich blamed the teen category’s performance on the unexpected plunge in music game sales in 2009, estimated to be a 40 percent decline compared to last year.  Read more at Industry Gamers.
