Webfoot Technologies managed to get the licence for Dragon Ball games purely by their CEO being at the right place at the right time.

The first Legacy of Goku title had the same development time as its two sequels, but the game's quality is noticeably lacking compared to its sequels. This is because the only people on the development team were a handful of programmers and an intern. The rest of the team that worked on the entire trilogy weren't actually hired until halfway through development of the original Legacy of Goku. A lot of their time after being hired was spent cleaning up and fixing what they could before release.

Everything made for the games, content not from the manga or anime, all came from Webfoot Technologies. Though the design doc had to be approved by Atari (publisher), Toei (licensor), and Nintendo. Everything they did required approval from all of them.

The team originally gave the games different names as well, with the second and third games being titled "Legacy of Goku 2: Future Shock" and Legacy of Goku 3: Buu's Fury" instead of Dragon Ball Z: Legacy of Goku 2 and Dragon Ball Z: Buu's Fury.
