The Dragon Ball Z: Budokai Tenkaichi series, originally published as Dragon Ball Z: Sparking!(ドラゴンボールZ Sparking!Doragon Bōru Zetto Supākingu!?) in Japan, is a series of fighting games based on the anime and mangaDragon Ball by Akira Toriyama. Each installment was developed by Spike, while they were published by Bandai in Japan and Atari in all other countries, up to Budokai Tenkaichi 3. From Raging Blast onwards, Bandai's role will now be filled by the merged Namco Bandai Games and Atari's PAL distribution network has been absorbed into Namco Bandai Partners. Namco Bandai will also handle publishing in North America for Raging Blast and all other games beginning in 2010, effectively ending Atari's involvement.
