I remember seeing printed ads on the endcap of a target electronics section that said "HALF LIFE 3" with a fake mockup of the packaging. How many decades ago was that now?
Well they have to finish 'Half-Life 2 Episode 3' before they could even consider working on HL3.. I have not been paying much attention to Episode 3 development, but boy they sure have been working on it a long time! I'm sure it'll be great when it finally comes out, hopefully soon!
