Looking to be the most in-depth DBZ game ever. Looks like it has the traditional story mode which features world map exploration and the like between fights as well as a Hero Mode where you use a character you created from scratch. It also brings back huge boss fights which have been missing from DBZ games this generation. They seem to be more like the one's found in Naruto Ultimate Ninja Storm where there's a ton of cutscenes and QTE's inbetween set pieces. I also like that they finally made new character models for everyone. They've had been using the same one's since last gen.
