Dragonball Z Budokai HD Collection is an updated version of both Dragonball Z Budokai 1 & 3. Why they did not include 2 in order to round out the trilogy is beyond me, as it would have added extra value to the collection. You can really tell the difference between Budokai 1 & Budokai 3 as soon as you start to play each game. The lack of online multiplayer and a different (albeit still passable) soundtrack leaves me wanting a bit more, but overall this is not a bad collection. There is a TON of content packed into each game.
Check out my video review above for the full details on what I thought, as well as some gameplay footage. All recording of the Dragonball Z Budokai HD Collection was done using the Roxio Game Capture Pro HD, which you can check out my review of right here.
This review was based on a physical retail copy of the game for the PlayStation 3 provided by Namco Bandai.
