Half-Life 2 is the best PC game I've ever played, period. The moment I saw the G-Man giving his introductory speech, I was amazed at the excellently crafted detail and facial animation. The physics are not just good, they're perfect. You won't see a car going halfway through the ground in Half-Life 2. The graphics are the best I've seen on my PC while gaming. Half-Life 2 brings out new ways of killing never before seen in other PC games. Instead of just shooting the enemy, you can throw something at him, destroy the object he's standing on so he falls to his death, push a washing machine off a ledge and crush your enemy or drop a crane's huge magnet on him, just to name a few. You can find so much detail in Half-Life 2 that you find something new each time you play it. However, this game is not for everyone. Little children (obviously) and people offended by intense violence and blood should not play this game. If you haven't played this yet, play it now.
