Can I skip the launcher on Skyrim?
Go to your Skyrim installation folder. The folder is usually under "C:\Program Files\Steam\steamapps\common\skyrim\data" or "C:\Program Files (x86)\Steam\steamapps\common\skyrim\data" depending on your system. In the folder, there should be two executable files named "SkyrimLauncher" and "TESV".
Rename "SkyrimLauncher" to "Launcher".
Rename "TESV" to "SkyrimLauncher".
Skyrim will now start immediately without entering the launcher.
As far as I know, neither Skyrim nor steam have any direct options to do this.
As a workaround, you could use the Skyrim Script Extender to launch the game.
You can add the SKSE to your steam library as a non steam game, then change the tile to the one from Skyrim and hide the original Skyrim in a Category.
You can copy/rename the files so that the real game executable is named SkyrimLauncher.exe
Works for me.
