Platforms are being made as maps are. Here's what we got so far for use in Demo 2:
Whenever a battle occurs, Platforms are the arenas where the Pokemon square off. Different platforms are used to denote the different environments the player encounters along his/her journey.
We plan to use more platforms than the standard Pokemon games to give each battle a more unique feeling.
These are the platforms that have a possible use in game. Keep in mind that they are all currently works in progress, as none have been explicitly finalized or approved yet.
