Dragon Ball Z Budokai: This game has been much improved graphically and good music still retains many games and gameplay options of the old but still a good innovation.
Dragon Ball Z Budokai 3: This game has been the best mejoradamente especially around graphics, also have included the old passwords budokai Collector Edition as king piccolo, goku halo etc. .. intros have improved even graphically.
What upset me most is that not to have included the Dragon Ball Z Budokai 2 but you can not improve much but as a Budokai Collection should have included. But it's a great game even for big games dons Gamecube, PS2 have become very cheap so you have to buy it.
