The game is 15 rating. My husband let him play it once, and I felt very uncomfortable about it.It is 'just' shooting, and my dh argues it's 'just like cowboys and indians', or pretend gun games that boys play. We've 'compromised' and let him play a 12 game that uses guns. When my ds is on x-box you can see what games his friends are playing remotely - and I'm pretty shocked that many of them are playing Call of Duty - and worse, and some of these kids are from the kind of families you wouldn't expect to be so lax.
So am I being unreasonable?
