Budokai Tenkaichi 3 was the best DBZ fighter ever made, Just wanted to insert my two cents there, anything besides that is a downgrade.

Moar Power.

They are all "OVER 9000!!"

Anyways, if the question was not a joke.

Super DBZ plays like street fighter.
Budokai is a fighter with some flashy moves and some rock-paper-scissors type scenes.
And the ps2 Tenkaichi series tries to mimic the anime the most.

I prefer the tenkaichi style(part 3) for its battle system and immense fan service. Everything after, was just milking the series.

Six year old thread.
