They need to make a DragonBall Z similar to the series. You know, where the characters spend 30 episodes (say around 8 hours) powering up, fighting for 2 minutes, and then going to back to powering up. (Can you tell I hate DBZ?)
HEHEHE... I still have bad memories about the Freeza saga. Freeza throw a fireball thingy at the planet and said: "In FIVE minutes, the planet is gonna explode." Meh, the planet exploded after 10 episodes! This means that each episode is equivalent to half a minute???
Anyway... I like some DBZ games though. DBZ Legends for PSX is a great one (on single player only. On versus mode, it sucks!). DBZ: Hiper Dimension for snes and the only DBZ game on the Genesis are also good. One of the best ones though is the saturn one (forgot the name, but plays like Budokai).
Well, to tell the truth, the BEST one IMO is... "DBZ: Psicomaniaco", a MUGEN DBZ game made by me.
