Capcom has blamed genre cannibalism as the reason for Street Fighter X Tekken’s less than stellar sales. The company confirmed in a Q&A that it believes the crossover has lagged at retail due to the large number of similar titles released within a short period.

The publisher itself has launched three versions of Street Fighter IV in the past four years. That’s in addition to NetherRealm’s Mortal Kombat reboot and countless iterations of BlazBlue.

Street Fighter X Tekken has sold 1.4 million copies to date. A Vita version of the fighter is set to release later this year.
