Not many teenagers are going to possess a $5000 desktop computer, properly equipped with a CPU & a GPU and a power supply, along with the expensive RAM and equally expensive computer monitor which would even remotely allow a powerful computer program (like this one mentioned) to load and seamlessly play well enough that the simulation is that much of an addictive draw.
I had not considered the actual/probable desensitivity which probably would accompany playing a game such as this for those kids who do have access to the hardware necessary to make the immersive experience workable. As you may be aware, I have no offspring around me to guide nor advise nor feed/clothe or take care of. But I've had numerous occasions to be around youth aged newborn to age 17 - and though I type and talk like a sailor - on adult websites and even out in public - when I curse, it's usually an unspoken thought - or heavily modulated depending on the audience likely to hear my voiced thoughts.
I don't/won't curse like a sailor around children. I also won't show any violent behaviour, make any verbal nor physical threats to others while in the presence of school to pre-school age kids. I won't participate in overnight booty calls with mothers who still have young children in their home. Not everyone thinks nor behaves like I do, though.
Missouri recently legalized recreational cannabis products for sale. A reasonable parent isn't going to make any trips to the dispensary to purchase flower or dabbing concentrates for their teen age children.
A reasonable parent isn't going to purchase a handgun with ammunition for their children, nor leave said equipment within easy reach and control of kids.
A reasonable parent wouldn't allow their children to access pornhub.
A reasonable parent would know almost exactly what their child or children were accessing (during their alone or friend play-time) via the internet, and set their limits accordingly.
A reasonable parent would not allow their children to glue their fingers and noses to smartphones or desktop super computers - while engaging in social media and computer games - and they certainly wouldn't allow their under 17 age children to engage in a first person shooter game - where the targets are reasonable facsimiles of human beings.
I believe that many of the aborrhent behaviors which plague our society - are taught or introduced to our children by their parents and older siblings. Sometimes that occurs willingly by parents who shouldn't be parents - and oftentimes by parents who are delegating parenting of their children to other people who really couldn't care less about impressionable younger/developing minds soaking up 99% of the stuff they see or experience - during their youth.
There's way too many parents out in our world who aren't prepared for the 24x7 responsibilities which exist when raising a child or a covey of children. It's become easier to throw the kids some coin every week and telling them to purchase whatever floats their boats - while the parent(s) are off doing their own things.
Simply identifying temptations and risks for children is only doing half the job. Advising/guiding/parenting the child(ren) and educating them as to why cocaine, or semi-automatic handguns or watching mysogynistic porn isn't good for your short nor long term health and mental well being - is taking the more time consuming steps which a lot of parents aren't even equipped to deal with over a 17 year period of time.
