Mind you this IS silly I know. Most of you already have a custom and possibly better then this. A user in our Steam chat group was wondering why there is no Icon so i spent 2 minutes and made this one using good ol' google. to get this as your source SDK icon... Download the .ICO from the attachment to this post and save it..... C:\Program Files\Steam\steam\games. all done, now on the desktop hit F5. You can create your own as well.
