Cons:

This is the game that reduced Fatalities to "Heroic Brutalities" for DC characters (e.g., Superman punching you into orbit) and softer Fatalities for MK characters (e.g., Scorpion's "Toasty!" simply melts you without dismemberment). For a PSP game, this T-for-Teen rating would have actually been a benefit , as it would have avoided the stricter content ratings that hampered other MK portable ports in certain regions.
