Well Madhav Gupta, sorry to break it down to you, but there is NO real life Pokemon world. It is all fictional. However, most of the regions are based off of real life cities and areas. See below:
The Unova region is based on New York City, USA, while the Kalos region is obviously based off of Paris, France.
Sorry there are no Pokemon, and no Pokemon world, it's fantasy and that's one of the bitter truths of life.
But then again,
Fingers crossed then. XD
