The problem wasn't with Stanley in specific, or even something as specific as the source engine. This was just the first 3D game I played after 8.1 installation. Should We update the tags and stuff to help more people, or just leave the question as is?
If, after researching the question, it can be determined that the original tags were unintentionally incorrect, it may be in the question's best interests to update tags and/or title.
I am less willing to endorse a changing of the question body, to make it fit the answer.
