Good but HARD!
Firstly, this is a hard game! Thats mostly why I set the age so high. Its really challenging; most kids will find this hard to master. I'd even venture to say a twelve year old, unless they are experienced with gaming, might struggle.
Great graphics, its an experimental parkour game that really did what no first person game has ever done before. There is violence, but very little is done by you. And there isn't that much, honestly....most of the time, you are running away from a kind of "Big Brother" governemnt that sends police to shoot you, and you disarm and run from them. You can also shoot back...but gameplay makes this exceedingly difficult usually and your best bet is to run.
Lot of fun. Not the best game I've ever played, but something completely new and certainly worth it, certainly. Difficult though. This is a hard game towards the end. Your kid will need really good fine motor skills and problem solving in order to get anywhere here.
