"...What's that, you say? That's impossible?"
"You're about to find out how wrong you are."
The year is 2018. Honestly, nothing much has changed. There have been no huge jumps in technology, no breakthroughs in science, or culture, or anything like that. It's about as present day as present day can get. For most people, the world goes on as it has, and as it will be.
You love to play video games. Some would use the term 'gamer' to describe you, but most people see it as a somewhat outdated term. After all, so many people play games at the very least casually that using the word 'gamer' to describe such a huge group is meaningless.
But no, you love playing video games. And you may play for different reasons. You might play it because it's relaxing, you might play to escape from the monotony of the real world. Some of you might place gaming as a higher priority than socializing, hygiene, and the like. Some of you might even be normal. But still, playing games is a passion for you, not just a hobby.
And you've watched the anime, or at least heard about it, right? Sword Art Online or, if you're really classy, Log Horizon? Those tales of players getting stuck in their game world and fighting to escape? No problem, you'd think. You'd go to town with an opportunity like that, right? But, technology hasn't progressed that far, and even if it did, there would be safety measures. There was no way the scientific community would allow something like SAO to happen.
There was no way some sort of supernatural force would do just that.
There was no way you'd be taken in your sleep.
There was no way it would be a game no one's ever seen before.
