i don't think it's been mentioned yet but the worst part of HL2 is the RESALE value, screw the replay value. Under the Steam EULA you are not able to sell your game. Its $50-60 flushed with no return. Lots of people buy the game the day it is released and beat it then sell it for $10-15 less. This is a shitty practice that I will not be part of again, I will not purchase something I cannot resell.
