Details on Pokemon Sienna


The story takes place in the Kanto Region where your character applies to become a trainer in the Indigo Plateau. Unfortunately, your application would be denied, but that’s okay. This leads to you starting your own adventure as you trek through Kanto and other Regions to become the best Pokemon trainer there is.

The Pokemon lineup in this game is a bit unclear because, for the majority of the roster, you get to use Fakemon. That’s right, you start off from three Fakemon starters and you’ll be fighting others along the way.

There is a couple of actual Pokemon but it isn’t exactly which ones are appearing from different Generations. The story progression is affected by the choices you make as well as other factors that come with it. It makes the game all the more interesting when you can choose one or the other.
