Can't touch this!
You have the chance to play through the story of each soul, even though at the end the last two characters they fight are always the same. Before each fight is a bit of cimematography, some of which requiring your input which will affect your health during the fight.
You can unlock many of your characters' weapons, outfits, new characters, and character creation items simply by fighting through each tale, but after a bit you're required to either buy them from a shop with the money you've earned or play chronicles of the sword for the remaining few that can only be had by playing through certain battles.
Another cool facet of this is that there are guides online for creating characters from other games on SC3. Like Ada Wong from Resident Evil, Kitana from Mortal Kombat and many others.
This is a game where you can just pick it up and play it, if you don't know the combos you can button mash and do some pretty awesome damage, or if you're so inclined you can decipher the moves list. (They didn't use the symbols on the controller, you have to learn what each letter stands for.)
The only thing that I'm going to dock this game for is that when you are in character creation the music is always too loud when you're trying to pick a voice for your character, the moves list is 'encrypted', and I don't know about you but I could never save my chronicles of the sword part of the game. It always said that the data was corupt. You can still permanently unlock the features that you earned by playing it though.
