I was thinking about ideas that Pokemon main series games have been based around in the past and was inspired to create this thread. If something like this already exists I apologize but this is supposed to cover all games and is a broad topic.
Pokemon games have included various concepts, for example Black/White and the concept of Yin/Yang/Balance. There are many concepts however that probably have not been explored by Game Freak. What do you think Pokemon games ought to incorporate in terms of inspiration and what they are based around?
