Which is a good Dragon Ball Z game

Dragonball budokai teinkachi 2 and 3. I have number 2, but I heard good things about number 3. On my one, the story has more than 60 missions (battles) and it lasts you for 2 weeks if you're really good, a month if you're just good and 3 month if you're average, of course this is if you play only this game. It includes a vs mode and a tournament mode which has 4 difficulty levels and 3 different types of fighting and it's really fun. There are lots and lots of characters, but honestly, sometimes you just keep doing the same thing: square square square. Overall it's a good game, but I believe that it's too much concentrated on the fighting for my liking. In fact it's only fighting, but it got me entertained for an year or 2. One thing I really enjoyed was fusing together 2 parts either collected after a battle or bought from a shop and getting a character out of it. I'd buy it even because it should be very cheap now, since it's on PS2 and it's kinda old. If you're into fighting games, buy it!
