Oh wow, I forgot they're so much behind my timezone. Silly me. Please excuse my post. But still, if they don't do anything at all then that's really going to suck :\
Wow, I can't believe Valve hasn't even posted anything about this to their website or Steam... I wasn't expecting a HL3 release date or anything like that but at least something like 'Happy birthday, Half-Life!'. They did that kind of stuff with TF and Counter-Strike.
Nice. Did you make that (judging by the number of views I'd presume you're the author because it's not very likely that you'd be one of the 36 other random people)? The animation isn't quite the smoothest but I love the style. The other video on the channel is pretty fun too.
