What Do You Mean by Non Steam Games?

The Steam store, made by Valve, is the largest games app store in the world. It features millions of different titles and the large majority of what is available on the internet today. However, there are three main reasons why a game won’t be listed in the Steam store:

  1. It is an indie game that hasn’t been added.
  2. It is a retro game that was created and distributed before Steam.
  3. It has its own game launcher from a Steam competitor company.
