Well, think about it.
It is just a video game, of course.
No matter how realistic it seems there will always be that thought of knowing you're not really in Equstria.
Even with that said, It would still be a awesome idea!
Would I want to return, Yes.
Like I said, it's still a video game.
You can't just continue playing it, and not worry about your real life.
In order to even make it worth playing, we would need to improve a lot in technology to make it seem like a real reality, outside of ours.
Still, a very good idea.
