...okay, that's a lie, but in this case it can actually be pretty cool. Today, we're going to take a bit of a different route(see what I did there?), and look at the regions throughout generations I-IV, from real-world basis to atmosphere and location. Before we look at the individual regions, however, let's take a look at the overall structure of the Pokemon world as we know it.
Kanto is where it all began. Kanto is based of the Kanto region of Japan, being the only Pokemon region sharing its name with the land it's based on. However, this name was not introduced until geeneration II. In gen I, the region's name was never revealed, and so many players assumed the region's name was Indigo, coming from the name of the Indigo Plateau. The region was originally portrayed as being largely grassland, but with the generation III remakes, it was redone into a more foresty region. Containing a warm, nature-freindly climate, Kanto has a more modern and technolohgical feel than it's neighboring region of Johto. This is evident by the look of many landmark locations in the game, such as the power plant and the Cinnibar island lab. Another poiont to be made in relation to this is the fact that Kanto is the only regions without any legends or cultural influences based around its legendary Pokemon. The people of Kanto are often thought to be very sophisticated and formal, in comparison to the other regions.
