So for our list we'll separate the titles by their respective decade. So as the series ended in Japan. It was the start of anime series in the West. It was also the start of game flood for the west. It was a little barren however.
Dragon Ball Z: Hyper Dimension. Released in 1996 for the Super Famicom. Now if you were in the import scene, you knew about this game. This game even by today's standards this is one of the best titles. It played as a well-tuned traditional fighter. The roster focused on 8 characters. So more detail was provided to their sprites, animation, stage design, music, and etc. Best game of the 1990s? -- Yep, it's easily in the top 5.
On the other end of the spectrum, we have Dragon Ball GT: Final Bout. Released in 1997 for the PlayStation, the title was a 3D fighter. It was one of the first fully 3D games for the franchise. Now, this game should be something you should pass on. The roster, although packed, felt very phoned in. The game play was mediocre at best and it looked unappealing. It belongs around the bottom of the barrel, untouched.
