Capcom released a fighting game of Jojo's Bizarre adventure in December for arcade. In the United States, the game is called "Jojo's Venture." The game is about part three of the story only, which is one of the most famous part of Jojo. The graphic of the game is very good. The picture above is the menu where you choose the character. The fighting game is available in most arcades now.
Also there's a Jojo game released a few years ago in Super Famicom. It's a RPG game and it is about part three too. But due to the low system, the game made little impact on the player. I got mine a while back, and it is hardly found in the market anymore.
