I was thinking about it recently on how great the setting are in each Pokemon Game. The First 4 regions are based on Japanese's regions and yet they look all different with Hoenn and Sinnoh being more Tropical and Mountainous respectively. As for Unova..i like Unova especially because of the verity but i do have problems with it. Kalos on the other hand is perfect it has a right blend of areas that are familiar to old players but also some very unique areas like the creepy forest. In my opinion Kalos is the 2nd best Region with 1st being Sinnoh. One last thing..I think Africa could be a really cool with both Egypt and Cape Town being very interesting areas to explore in Pokemon.
