Parents don't have much to worry about in the game. It's a little violent, but in a mostly cartoonish and inoffensive way. Nearly any player in their teens should be fine.
Fighting Gamers will only be interested so long as they're big fans of the relevant franchises, and even then there are better Capcom vs. SNK games out there.
Fans of 'Engrish' will find some kitsch to amuse them—each fight begins with the encouragement to "Play in real earnest!"
Xbox Live Players might want to give this game a look, as it's an interesting experience, being able to Street Fight against people on the other side of the continent.
Deaf and hard of hearing gamers will be fine—the game's limited story is all presented in text form, and all relevant information is displayed graphically on screen.
