dragonball z

does any one like those games and why and if you mind saying why

Do you mean all DBZ games in generall? Then, yes I like some of them.
Why? That' s like asking how life first arrived on Earth.
I guess you should have read or at least have some knowledge about the manga/animé DB and DBZ.
Playing a game where your favourite characters from a cartoon is in, is simply fun.
The gameplay in a DBZ game isn' t exactly the best you can get but it' s functional, escpecially if you play the games with some good friends, preferably fans of the series.
The DBZ games differ from other fighting games in that they are crazy... just like a lot of manga/animé.
However I think the latest DBZ fighting games (Budokai series) are the worst DBZ games so far. The old SNES games are MUCH better, as well as the RPG,s for GBA.
Right now I' m looking forward to buying Ultimate Spider-Man, another cartoon game. But it looks more promising than Budokai.
