that dragon ball had only a few more hundred entries than street fighter v and the games is new with a big brand attached to it that attracts casuals
street fighter v already been out for years and still going strong, all the other anime fighters are irrelevant, Dragon Ball is big because Dragon Ball is the star wars of anime, any game with dragon ball attached to it well be popular.
All the top players and biggest names in FGC play street fighter V, that is the sport period, there's a reason sonic fox can dominate every other game but Street fighter V, because all the best players play Street Fighter V there's a lot of competition
The finals true more attention with Dragon Ball because Sonicfox was in the final, if he had been eliminated they wouldn't have been viewed as high
Street Fighter V was still the main event and will always be the case it is THE fighting game
If Daigo and Tokido were in the Finals, it would beat Dragon Ball Z in the ratings, if Punk was back against Tokido or any other name it would've been the same, Problem X is a solid veteran but he ain't got the clout like many other names, so it didn't generate as much hype
