A while back a bunch of Valve fans started a Steam Group named A Call for Communication, this is basically them just wanting better communication between Valve and the fans in question. This is all Half-Life 3/Episode 3 related as fans are becoming seemingly impatient with their wait for the return of a certain Mr Freeman. Along with fans making this page along with a Facebook page, twitter and a Steam forum thread. We have also seen Operation Crowbar put in to place as well where fans bought and sent crowbars to Valve HQ as yet another not so subtle hint.
Now it would seem they are going to try and get Half-Life 2 to the top of the most played list on Steam as an attempt to grab the attention of Valve. This mass play through of the Valve game is set to start at 7pm gmt (11am pst) this Saturday. I am actually playing through Half-Life with intentions of moving on to Half-Life 2 once I have finished. I believe I could finish off the first game by Saturday and join in with this. If anything, it's an excuse to play through the game again.
