I strongly disagree with the T rating this got. I would have rated it E10+
sure, it's a fighting game, bit there's no gore and all that happens at the most is you fall off the screen (most of the time you might just fly back) I think a 7 or a 8 year old could play this game.
great for 7-8 or older
violence, but no gore
non-realistic violence (no-one shouting, screaming, falling to the ground in a realistic way for death)
lots of martial arts
nothing else inapropriate (no language, sex, etc)
