The story of No Game, No Life centers around Sora and Shiro, a brother and sister whose reputations as brilliant NEET (Not in Education, Employment, or Training) hikikomori (shut-in) gamers have spawned urban legends all over the Internet. These two gamers even consider the real world as just another "crappy game." One day, they are summoned by a boy named "God" to an alternate world. There, God has prohibited war and declared this to be a world where "everything is decided by games"—even national borders. Humanity has been driven back into one remaining city by the other races. Will Sora and Shiro, the good-for-nothing brother and sister, become the "Saviors of Humanity" on this alternate world? "Well, let's start playing."
The story looks kinda unique to other series (Unlike sword art online and database).
One posibility is that the main character (and his sister) go in coma due to much gaming. And after this they are stuck in this fantazy world (well this is how i would explain teleport into another world....). And they are probaly in hospital stuck on life support. (explains how they survived the fall)
For a 1.st episode is interesting (but story goes too fast). I will have to see more to judge but i give it 4.2/5.
One gaming coma sorce:
