Sorry but thats a ridiculous comment. Half Life 1 is just as timeless as Half Life 2. The graphics may be dated but the gameplay is still top notch.
It's actually not, if you go an play it now. I'd never played Blue Shift, and when I tried it a few months back I only lasted an hour or so. I gave up when confronted with a box stacking puzzle. The graphics didn't bother me in the slightest, but being asked to stack boxes with a crane to reach a switch just felt very old.
