Honestly, I feel most fans of the Dragon Ball series got into it around Z, for a variety of reasons. Increasing popularity of the IP and an increase in the ways someone would be able to stumble upon it for sure helped; a perfect example being Toonami, whoch you alluded to. I know for me, as someone who grew up without easy access to cable TV and manga, the bulk of my exposure to DBZ's story was actually through the GBA games. Proud of you for getting this one out, I know how hard you were working on it
