I wanted to put this in the General, but then I'm pretty sure a Japanese only game wouldn't make sense for General, so it's here in the fun threads.
Dragon Ball Heroes is a Japanese arcade game that features over 150 unique characters spread though out hundreds of collectable cards that can be used for the game. You can have up to a team of 5 characters to fight other teams. There's also a ton of obscure, what-if and new Dragon Ball characters in the game as well!
This is the trailer to the latest version of the game:
The latest confirmed characters seem to be Kid Goku, Kid Krillin, Young Yamcha, Master Roshi, Pilaf Robot, Ninja Murasaki, General Blue, Pirate Robot, Kid Pan, Big Gete Robot, GT Gotenks and Liu Xing Long/Oceanus Shenron based on this trailer and some magazine scans.
Any thoughts?
