So I decided to download The Stanley Parable after seeing it mentioned in an old review video I was watching. I downloaded the zip, extracted it to the
steam/steamapps/sourcemods folder, restarted Steam so it would show up, and when I click "play", nothing happens. Literally nothing. There are no new processes starting and getting hung up, I don't get any indication that clicking the button does anything.
Is there a way I can get it to work, or am I just out of luck?
