Soulcalibur: Broken Destiny is really for the fighting junkie only. If you can't ride a bus without getting your fighting fix, this is the game for you. Otherwise it's just another port. It's a port of a great game, but in this case, the portability factor doesn't make up for what you lose in the transfer.
The lack of a fun, simple versus mode and the absence of a story mode take away one of the biggest selling points for any fighting game: the replayability. Without it, this is just another game that the PSP faithful will buy in hopes of justifying their purchase of the hand held in the first place.
