Playing blazblue allowed me to apply fundamentals to street fighter , kof and even tekken. I did not play fighting games seriously till i played blazblue. Played Guilty Gear and soul Calibur 2 when i was in high school i button mashed my way threw them. If it were not for blazblue coming out i would have hated fighting games. When Blazblue came out something made me want to learn how to play that game. Now i can play most fighting games on the basic level with out button mashing. But i still have a long way to go. Never stop improving and just work on being better and learning from mistakes. As many other people in this thread said play blazblue to master blazblue. Kof or street fighter will not make you better at blazblue.
