I agree- Bandai just cannot make decent DragonBall Z games - the last decent one I played was on the Famicom (Japanese NES), oh like 15 years ago (it was a card-based game).
Yeah i LOVE DBZ, but I ahve yet to see a decent game come out.... they need to get one fo the good developers out thtere to make a go with it, all the ones i ahve seen so far have really had the feel of "weeeee lets cash in on DBZ popularity and reuse some old engine"
I always thought Bandia should have licensed the rights to DragonBall to Capcom to make a fighting game like X-Men vs. Street Fighter - DragonBall vs. Capcom - now that would have been cool.
