Lots of great 3D animation, hype moments, and they played the fucking opening during the final fight with the ultimate SPARKING segment. Basically a culmination of the entire adventure with Goku finishing the final boss with the classic Spirit Bomb and Vegeta getting the best character development possible.
It's hard not to feel emotional because of just how well they handled the ending in video game format. I know there's like a million fucking DBZ games, but this one is easily one of the most polished and pays its respects to the series in a really cool way.
