Dude the whole Half-Life series is fucking amazing. Half-Life 1 is a blast to play through and is really really good, but Half-Life 2 is perfection. The art direction, the tension building, just the general feel and atmosphere of the game is unmatched.
Honestly if you have played through the series and all the episodes and can still say that then I would be floored. If you haven't beaten all of the above then I would strongly suggest giving it another go on a proper gaming machine...I'm talking about a big ass screen, loud speakers, a bowl of dank, and the lights off.
