Yesterday I finished hl2 in just 6.1 hrs without abusing a single exploit, and was honestly quite proud of myself. So I wanted to know what everybody else's fastest is.
The first time I played through I took (spread out over a week or so) 12 hours. I thought I did this quite fast, so I went through a second time, thinking "I'll do it slower this time, and pay attention to small details", and put it on "Hard" difficulty. I got to a save point a bit into the game, and looked at my old times for saving at the same part.
I had halved the time it took me the first time - and this was supposed to be me going slow! I guess I must have remembered what to do from the first play!
I dunno, discounting playing an odd level here or an episode there?
I've only played through HL2 twice, and I was never rushing either. HL2 is like a fine wine, it must be savoured and its full spectrum of flavour and aroma experienced and appreciated. :imu:
