I never finished the original Half-Life, this game really brought out all the stops in the atmosphere department. A friend told me that he would've preferred if I played the original then followed by HL2 to see the progression, looking back on it I'd probably agree with him but this game is genuinely very quality. Crowbar Collective did this game justice and I hope they put out some original works in the future.
