1) Run the game at least 1 time via the launcher and to set the graphic settings you want. After this step you will never need to deal with the launcher again unless you uninstall/reinstall the game.

2) Head to the local directory for your game. For me it's in a custom location, for others it will be in your C drive. Look below for an example:



3) Click the directory bar and copy it.

4a) Right Click Atelier Ryza in your Steam Library.

4b) Click on properties.

4c) At the bottom of the "General tab", you will find "Launch Options" and a text field.

4d) Write in this field "FULL GAME PATH TO .EXE FILE" %command%

EXAMPLE:
4e) Close the window.

5) Enjoy!
