This is... very unexpected to say the least... or at least I didn't see it coming. Suddenly I somehow look even more forward to this game than I already did.
As for dialogues in fighting game, they tend to be at least a little more "complex" than what's seen in Danmaku titles. Even with a limited amount of dialogues, one has to figure out the plot for each characters, all dialogue bits, everyone they encounter, dialogue bits after each fights in Vs. mode and then there's the endings. It might not seem like a lot but figuring and planning everything out can be a surprisingly big amount of work.
