There's generally the reason why a FG does not get featured at an offline tournament. Lack of support due to apathy or people rather staying home or playing online.
Well games like MK and Injustice don't have the biggest showings but MK was at evo 3 years in a row. and injustice will be at evo for the 2nd time as a main game. Not trying to compare but I was just surprised to see the lack of SC support because I find it really enjoyable.
