I plan on buying Guilty Gear when it comes out this gen, and I'll buy Persona 4 for the same reason as you. FGs and Persona, yes please. so I am going to give this sub genre a fair chance.
yeah like I said I don't know anything about Blazblue. actually I'm kind of bad about FGs in general. If it isn't ST 3s or CvS2 I probably don't know anything about it. I have heard that GG is one of the most respected games though and that it still has an active scene in Japan and a semi-active one over here.
