Fans are happy that Dragon Ball: Sparking Zero does not discard the feature they have long experienced in the past. The fans are not happy because the developers have limited to only one level. But, yes, the fans, as we know them, are full of hope.
The split screen from the Budokai Tekaichi series is useful in the Hyperbolic Time Chamber in the upcoming Bandai Namco game. But fans, as seen in a conversation over social network Reddit, believe that developers may not really be keeping the feature to just one level.
As the saying goes, always be hopeful, and the things we believe in may come through one day. The fans seem to follow just that. They believe that the decision to keep the split screen in the Hyperbolic Time Chamber may not hold.
