While its budget price may make Infinite World a tempting purchase, previous DBZ games on the PS2 have tread this ground already, and have done so with much more robust fighting systems. You would be better off revisiting Dragon Ball A: Budokai 3, a superior game where the series' fast-paced combat was used to much better effect.
Dragon Ball Z: Infinite World is the worst Dragon Ball game Game Reactor has ever had the dubious pleasure to review. The game industry almost destroyed the mental health of all their writers. Avoid this game at all costs.
WorthPlaying: "I was really disappointed with Dragon Ball Z: Infinite World, and I already wasn't expecting much from it. Sure, the roster is impressive, and it definitely covers some unique characters, but playing the game feels more like a chore and less like the fun fighter it should be. The addition of non-fighting levels is a step in the wrong direction for the series. Fans should definitely avoid this one, even if they're dying for a new DBZ fix, as this title is likely to turn you off of the series for good."

A return to the past, a critical support for the Burst Limit and a large gathering of people. Infinite World is not as infinite as one might think at first, but ... Is that a reason powerful enough to allow the fans to stop practicing his "Kamehameha"?"
