FighterZ is only popular because of 3 reasons: -It's called DBZ -It's the most recent fighting game. -A lot of DBfighterZ fanbase never probably touched a fighting game until it was out, so they never bothered with arcs previous titles like GG, BB, or SNK KOF and so on...now more people are aware of other fighting games. That being said, so far you're right though FighterZ is the main title for now, until BB cross tag and especially Soul Calibur VI comes out.
