I just started up HL2 again for the first time in months and I noticed that the game was made in 2004. Wow. It's four years old and still incredible. Better than anything else released in the last four years without a doubt. I didn't really think about it before today, but looking at that and then jumping into Ravenholm for some shooty/scary action I was, once again, blown away by the perfection in this game.
I can only hope that
L4D proves to be as good as Halflife 2.
