I love Super DBZ, I remember when I first got it and played with my cousins. They complained because they said Budokai 3 was better. I forced them to play it with me anyway because I was really digging it. I'm an 80's kid too who cut fighting game teeth on Street Fighter and Street Fighter II, so the controls came very natural to me. I loved battling on Guardian's Lookout and kicking my opponent off the edge and all the way to the bottom where Bora and Upa live. That game was full of depth and win. I have two cousins who played it with me. One of them just kept getting agitated and insisting that we go back to Budokai 3. The other one kept fighting me, and complained about me always grabbing him with Piccolo and calling me cheap. I paused and told him not to let me do that then, find a move that counters it and stop me. He kept playing, silently practicing. He favored Trunks, and eventually discovered a dirty little sword combo that would counter Piccolo's grab move. The smile on his face was priceless, I could see the lightbulb go off, and he started to appreciate the game for the depth of gameplay, and quit being put off by the lack of flashy all out ultimate moves that his brother just couldn't or wouldn't take the time to get over.
I haven't played the game in years, simply because I have no one to play against anymore. If any game were a candidate for release on a new console with online play, I'd say Super DBZ would be one that could find a new audience that never gave it a chance a gaming generation ago. Super DBZ is a balanced fighting game that happens to have DBZ characters in it. It also has more manga influenced graphics and coloring schemes that is unique to it, as opposed to the Anime focused graphics and coloring in all other DBZ games.
Super DBZ is the diamond in the rough among a sea of over-saturated, over-sequelized DBZ titles.
