Okay first off what kind of situations do you put your kids in where there's a very probable chance they will see someone with a sword??? You know cuz you said you don't want your kids being scared any time they see someone with a sword..... Like seriously??? Secondly..... Because someone plays a video game, even a fictional first person shooter.... Doesn't mean they are gonna have their life lead towards violence. This is where people need to step in and be parents.... It's really that simple.... Be a f-ing adult and explain shit to your kids.... This is a fictional game, with a fictional story, and in no way relates to real life besides being a form of entertainment... If that's too difficult than you shouldn't be a parent in the first place.
