I don't know if this has been posted before, because I keep getting HTTP 500 errors when searching, so OnRPG seems to be having problems. Anyeverhow. From the site:
The Dragon Ball gang is at it again and this time in an all new and shiny Dragon Ball RPG game, how cool is that? The game is set in the Dragon Ball world about 250 years after the original show takes place. The graphics of the game have a retro feel as the comic style to it to make it seem more similar to how the original Dragon Ball once was.
Become part of the epic Dragon Ball adventure today and see what you can acomplish! Play as similar characters from the Dragon Ball Z show such as Goku, Gohan, Trunks, Vegeta, and many more. You'll be able to finish quests, roam around the Dragon Ball world and even duke it all out with other favorites in awesome Dragon Ball style battles!
