The Pokemon Brilliant Diamond and Shining Pearl remakes were designed in very specific ways, so many fans could enjoy the Sinnoh region in the same way that they remember from sixteen years ago. This included things such as the National Dex, the Poketch feature, and others, along with the classic Pokemon creatures first seen in Sinnoh. One fan decided to play the game with their favorite Sinnoh Pokemon, Cherrim, all the way to the very end.
