Ok, first of all I've been waiting for this sale for so long to start playing HL2 and TF2, as I've heard both were great games.. It's on sale for $7.50 at steam only today so grab it if you're in the same situation!!
Anyway just wondering if the order that the single player HL2 campaign should be played HL2 --> HL2:e1 --> HL2:e2, and also where does lost coast come in? I heard people mentioning that I should also play Portal before HL2:e2, why is that, I thought they were completely different games.
