Valve didn't start getting good until TF2 and Portal came out.
*dap this*
Of course, I need to get around to playing Half-Life 1 classic (NOT SOURCE) eventually. But I agree. I didn't care for anything Valve released until Portal and TF2. Half-Life 2 was
majorly boring due to all the physics stuff. Good for a tech-demo of their engine, but making an entire game of that and traveling in vehicles?

And then Episode 1 somehow out-bored the base game. 2 would've been amazing if it didn't take the driving and have you micromanage like three-four things with that last battle of driving, resupply ammo/gravity gun "ammo", fight monsters while managing health.
