There is a fan concept that is called Pokemon Call of the Trainer. With this, players will be able to roam over the open world and catch any Pokemon as they please.
The one and only goal of this concept is the following: dunking the Trainer in the world of Hyrule and adding Pokemon to the right places. The creative mind behind this also envisioned that instead of the powers of the Sheikah tablet, there would be many different actions that would be available in the Pokemon games.
This fan concept got attention when Eurogamer interviewed Game Freak director Junichi Masuda. He was asked about the possibility of an open-world Pokemon game. Of course, Masuda did not give a clear answer but left the door open for it in the future. This interview also threw oil to the flame, which led to fan arts of this concept.
The fans tried to imagine what would this all look like by photoshopping Pokemon into the world of Breath of the Wild and you can see the final result below.
Who wants to see this as the next Pokemon game? I know do!
