It's not a huge deal, and I don't want to make it sound like it is. But personally, I'm uncomfortable with military shooters because of their context. A while back I read the
interview Gabe did with his grandfather on WWII themed games. It was an interview he did back in 2003 after Call of Duty came out. It made me realize how people who had been through war saw these games differently. I was never fond of the genre, but the interview affected me. And it made me think about my kids - who do not have a proper context for what realistic warfare is about - could be affected by it. I didn't want them running around shooting Marines. Or, for that matter, other people, at least not in a realistic way.
It's one of the reasons I'm comfortable with my kids playing Halo, and not Call of Duty. For the most part, their time with the game has been limited to just messing around together in Halo 3's Forge mode doing silly stuff with man cannons and grav lifts and mongoose and hammers. But now that Natalie is old enough to romp in campaign with me, it's a lot easier for her to understand "shoot the purple aliens" rather than "shoot the people with accents". I don't want her first serious exposure to realistic warfare to be in a video game.
Gabe's grandfather made the comment, "I think they can make games that will interest kids, that dont have to include war. We dont need to be killing each other in games. Theres other ways of strategizing and using the kind of skills that make those games popular."
That's stuck with me since. So I'm fine with people killing aliens, and players fighting each other in a stylized MP setting such as Halo's. But there's an aspect of something like CoD that I'm not going to bring into the house. Partly for me, and partly because I don't want my kids' first contact with war to be in games like that. Especially with
actual wars going on right now that are killing people, and which I struggle to explain to them. Given the abundance of games out there, and how few I buy these days, it's not a big deal.
