It's amazing, I can't wait to play it. Odds of it coming out in Sept is slim, VALVE has delayed everything they have ever made lol. But HL2 and Doom3 mmm. Its a new era of PC Gaming and Game Development. I got a friend who worked with some beta testing on HL2 and he just said prepare to be blown away.
