An URL that is all parameters
You can go directly in your View's settings, in "Page settings" bloc, configure the path manually. Just remove the game part of the path.

For your information:

I suggest you to take a look at Pathauto module that allows you to define URL patterns very precisely for all the default pages of your site (but not views apparently): https://www.drupal.org/project/pathauto


  The Pathauto module automatically generates URL/path aliases for
  various kinds of content (nodes, taxonomy terms, users) without
  requiring the user to manually specify the path alias. This allows you
  to have URL aliases like /category/my-node-title instead of /node/123.
  The aliases are based upon a "pattern" system that uses tokens which
  the administrator can change.


Maybe it will be helpful for other cases.
