Dragon Ball Z: Budokai Tenkaichi, originally published as Dragon Ball Z: Sparking! (ドラゴンボールZ Sparking!, Doragon Bōru Zetto Supākingu!?) in Japan, is the first installment in the Budokai Tenkaichi series. The game is available only on Sony's PlayStation 2. It was released in Japan on October 6, 2005, North America on October 18, 2005, and Europe on October 21, 2005. It is now a Greatest Hits title.
The game features 56 playable characters in 90 forms and 16 stages for battle.
Despite not featuring the original Japanese music, the American release of the game allows for selectable English (Funimation Productions cast) and Japanese voices, while retaining the English-language written dialogue (as adapted from Steven J. Simmons' translation from the original Japanese version's script). However, there are known bugs in the American version of Budokai Tenkaichi that cause pieces of English and Japanese spoken dialogue to cross over into whichever selection the player is using at times.
