I bought this game for my 9 year old son, Kevin, with some trepidation. I wish I hadn't now. Within hours of playing it for the first time, his eyes had taken on a fixed, murderous stare, and he started to mutter words like "die". Within 24 hours he'd started smearing mud over his face and wearing foliage in his hair, grunting at his siblings. He is now, just 2 days later, living somewhere in the woods behind our house, last seen with a hunting knife between his teeth carrying a hand made crossbow. Be careful.
