I think my last DBZ game was Hyper Dimension for Super Famicom and Dragon Ball Z Legends on PS1. After that I kind of retired DBZ around when GT came out. I was one of the "if its not Toriyama I'm not interested" people.
You missed out on some good titles! Older DBZ games are pretty cheap these days, especially PS3 releases. If you ever get bored I would encourage you to check them out!
I'll definitely give them a look. Thanks.
