What Tetsuwan Convoy said, Hokuto no Ken has this game which likely features most of the characters they've made figures of.

I'm not a fan of Hokuto no Ken, but I gotta admit that trailer is awesome.

Figurewise I've really enjoyed the Sengoku Basara figures, and these new Trigun ones look to be simmilar quality, I plan to grab them on my holiday, hopefully at the Kaiyodo store if it still exsists.
