My son is 5 and absolutely loves this game. As previously mentioned it is challenging enough to keep him happy for hours, but not too difficult so he doesn't end up frustrated!! If Ben 10 runs out of life he just starts up from where he perished, another plus point in my book as it's annoying for youngsters when their character "dies" and they have to start all the way from the begining. The two player option is really good as each player can join and leave without affecting the other players game. All in all a very good game for any Ben 10 fans, but probably not challenging enough for more experienced gamers....
