Gorgeous environments...and almost every graphical effect possible is used.
Without a doubt, the jaw-dropping graphics are what ultimately sets the game apart from its peers. Rarely do GBA games push the hardware this much, even those published by Nintendo. The sharp 2.5D backgrounds put the system's full 32,000-color palette to use, the character sprites are large and fluidly animated, and the bosses are downright huge.
There may not be any logic to Goku fighting a dinosaur, a giant robot, or a two-story scorpion, but it sure makes for exciting video game hijinks. Throughout the game, effects such as line scrolling, transparency, and scaling are employed frequently. Some of the environments are fairly creative, particularly those that involve raft riding or flying through the air. Fans of the cartoon will also appreciate that the game's graphics are faithful to the cartoon's art style.
The audio doesn't quite achieve the same splendor as the visuals do, but the music and sound effects nonetheless do an ample job of backing the onscreen action. Each stage has its own music, and there are plenty of different sound effects for attacks, screams, explosions, and the like.
On the whole, Dragon Ball GT: Transformation is a solid beat-'em-up and one of the better Dragon Ball video games available for the GBA.
