Wow. Some of the stuff listed here just amazes me. I really must be a sucker for some of this stuff. First of all, the "First Appearance Vegeta" figure was a really neat idea that got me to buy two frickin' Nappa figures. Perhaps you just got a bad paint job,
Tanooki Kuribo, because I really like this figure. The head is at a bit of a weird angle, but otherwise my figure's face and such look fine.
Also, I felt that "Dragonball Z: Harukanaru Densetsu" was fun, if not overly simple. I played this game to completion
(although I don't remember if I got all the cards) and really enjoyed it. It won't win any awards, but I definitely got my money's worth out of it.
I'm shocked to see that both "Budokai 3" and "Tenkaichi Budokai 3" are both listed here. I enjoyed both games immensely (although I think I prefer B3's fighting system to BT3's) and was totally psyched to be able to play as more obscure characters like Paikuhan and Janenba especially as I don't have a PSP to play the "Shin Budokai" series where guys like these first appeared.
To stay on-topic, I would have to say my worst DBZ-related purchase would have to be "Dragonball GT: Transformation" for the GBA. I trudged through "Legacy of Goku", immensely enjoyed "Legacy of Goku II", and really liked "Buu's Fury". Imagine my surprise when I picked up this game only to realize that it was a bad "Final Fight" clone. Maybe I just never gave this game a fighting chance
(pun intended), but I was really disappointed in it. I guess I wasn't alone as they were supposed to continue the series and never did.
