So let me ask some questions.

Did anyone from 1C even look at the steam website? Have you looked at it lately?

Do you see the massive list of probably not supported cards?

Did it occur to anyone to even look at the steam site after you got them to change the OS requirements?

How long did the steam site have the OS requirements wrong?

Did you expect to actually sell your game on steam?

Why is there still no PhysX?

Why have several people not been fired? Assuming they have not been.
