Wow, I didn't expect the killings to be lasting that long.
I would play through it, but I just imagined it with the screaming, etc that they wouldn't be able to get home anymore.
The fact that you had it so realistic, made it seem worse than playing GTA, because it honestly felt like you are killing innocent people, with all the blood splatters etc.
I'm not sure if it'd bother me. I'd surely be thinking about stuff while playing through it, but I think if any human didn't, somethings wrong.
