Also, NetherRealm Studios had utilized cinematic storytelling for the story of Mortal Kombat 9 way before Capcom had done the same with Street Fighter V back in 2016. As good a Street Fighter V was it was not quite as popular as Super Street Fighter IV which was released for the PlayStation 3 along with the Xbox 360 back in 2010.
Also, Mortal Kombat 9 had more of a cult following following its release than Street Fighter V did and was considered to be a better game than its sequel Mortal Kombat X which came out in 2015. Also, Street Fighter V had popular characters such as Sakura, Guile, Akuma and others as DLC opposed to them being unlockable characters in the game. Mortal Kombat 9 had almost every character you could think of from the first three Mortal Kombat games were available without DLC making a more desirable game to purchase following its initial release.
