I don't know what triggered it, but on Friday I had a sudden urge to play through Half Life 2...
Ah wait, I remember now. I'm currently playing through the 3rd chapter, with the airboat and it's proving to be a lot of fun. The second time round, you notice the scenery a lot more - or maybe it's down to everything looking sooooooo much nicer. I mean, the water actually looks like water now and there's bump mapping galore - not to mention no jagged lines anywhere.
The only thing I'm not looking forward to is Ravenholm. That section of the game never liked me and I never grew fond of it...
