My 10 y/o son LOVES this game! I am usually pretty careful about how much and which video games I let him play (this is the only "T" rated game he has, and he only has 1 E-10 game, everything else he has is "E" rated). The action/violence level is relatively tame -- all cartoon characters battling eachother, no blood, no visible injuries, the character who loses the battle kind of flies out of the scene. The battling itself isn't very graphic, with highly fictionalized "weapons." That said, my son and his friends love the game, lots of interesting "level-ups" and plot twists, plus fun characters you'll recognize from elsewhere.
