Actually did put time into Dragon Ball FighterZ, beating one of the story arcs they have. Sadly it's pretty boring so far. The entire first arc, all like 2 to 3 hours of it (I left the game running abit, so can't tell for sure), and its almost entirely a tutorial. You do get fights without battle tutorials, but they are almost all braindead AI. See an enemy twice your level? Don't worry, you probably won't die. They hit harder, but the AI is nothing here. I really don't understand what they were thinking as they have a proper tutorial mode people can go play. I don't need to be two hours into the games plot and still have to practice how to backdash. The design of the singleplayer is boring too, and kinda lazy, when I think one of the Budokai games already did the multi-path board game aesthetic, but I think they did it better or at least had more to do.
What saves it as a Dragon Ball fan, is all the interactions between characters, saying stuff that made me laugh or chuckle, and that it is an original story. So far, it doesn't seem like a particularly good original story, but when nearly every Dragon Ball games rehashes the same god damn story from the Saiyan Saga to the Buu Saga in practically every game, getting anything that feels new is a godsend. Being a fan is what makes it watchable, but if someone doesn't care about the story or characters, people are just gonna be bored.
I mean everything else about the game is fantastic. Best playing and the best looking DB game ever. Top notch music, gameplay, lots of good stuff here outside of the story mode. Just don't expect much out of the story mode unless hearing Goku and Gohan talk about fusing sounds funny and entertaining lol
