Every day, what will keep you going is just remembering that black box being on your doorstep one day. You stare for a moment, then open the long awaited beauty...
Just run the scene 10 times every time you become sad of the slowness!
HL2 is something you can play over and over (high replay), just because of that damn gun that picks things up! Plus, the firefights and such are always different since they're 'not scripted'.
HL2 is the reason i'm getting a new PC.. :P
