let's face it, Half Life 2 could never live up to the expectations the media and the general public set it. It was supposed to be as revolutionary to the First Person Shooter genre as Wolfenstein 3D was all those years ago, but of course, HL2 did not live up to those expectations for the simple reason that it COULD not live up to the expectations that were set, they were too damn high! And the same damn thing is going to happen to Aftermath, which should (emphasis on SHOULD) be an improvement to HL2, but will never, and i mean NEVER be as good as everyone hopes...
...and of course, it doesn't help that Steam, a vital component in the Half Life 2 "experience" is about as popular and useful as the dreaded BSOD...
