Zenkai Battle Royale

[Super Buu]

Wikipedia gave me no info on the game except what Vad said and the fact that apparently it's still played online against other players despite being arcade-only. Which sucks because it basically looked like they finally did a Budokai Tenkaichi game mixed with the Smash Bros aspect of having more than two people fighting. And apparently that the online software is called GGPO which stands for Good Game Peace Out. lol
