After installing Evolution you may want to assign it as a non-steam game. It will make opening the game much faster as it allows you to launch it from Steam directly, instead of always using the Launcher.

Please keep in mind, in order to update Evolution you will still need to open the launcher.

1: Open Steam, and click Games, then Add a Non-Steam Game to My Library

2: Click on Browse and Locate the game

3: The default path is:
C: -> Program Files (x86) -> Steam -> steamapps -> common -> NARUTO SHIPPUDEN Ultimate Ninja STORM 4

Click on NSUNS4e.exe and click Open

4: Click Add Selected Programs. if you did this successfully, you will see NSUNS4e in your steam library.
