Just started On A Rail.
I often think of Half-Life 2 as being my favourite game of all time. I'm not exactly sure why and can't express my feelings for that game, but I guess it's because of my memories of the first time playing through that game: it was like nothing I'd ever played before and it blew my young mind.
My dad managed to pick up Half-Life Generations after I completed Half-Life 2, but the original Half-Life just didn't have the same atmosphere I was looking for. Also it was bloody difficult for me at the time. (I was 11 in 2004!)
I think I remember only getting up to the end of On A Rail in the original, which is where I am at in Black Mesa now.
I have to say, I'm starting to think Black Mesa is greater than Half-Life 2. I think I'm starting to understand why some people think the original is better than 2; whereas before I just thought Half-Life 2 was the best thing ever.
If Black Mesa gets any better, I may consider it one of my favourite games ever.
I just wish Half-Life 3 was out by now.
