I dunno. They're buffing the HL2 sales figures by packing it in and selling to people who already have it. Ep 1 was kinda cute, but I felt really screwed when I realised that trivial battle was the big finish. (The sheet metal caused me to get blown up more than the foe) TF2 is amusing but it doesn't really hook me. Portal is an unknown quantity, and that's pretty much the kaboodle.
