The developers at Dimps had fun with the Dragon Ball franchise when they made the Budokai fighting games. Then Spike (now Spike Chunsoft) took Goku and the gang back into the arena fighting subgenre for their Dragon Ball: Sparking series (though in the West, the games were renamed to Budokai Tenkaichi to play off Dimps games). People thought the series ended after Tenkaichi Tag Team came out, and DBZ moved to other developers.
