6. Half Life 2
Half life 2 is no doubt the most anticipated pc game of all times.
Physics - From pebbles to water to 2-ton trucks respond as expected, as they obey the laws of mass, friction, gravity, and buoyancy.
Graphics - Source's shader-based renderer, like the one used at Pixar to create movies such as Toy Story® and Monster's, Inc.®, creates the most beautiful and realistic environments ever seen in a video game.
AI - Neither friends nor enemies charge blindly into the fray. They can assess threats, navigate tricky terrain, and fashion weapons from whatever is at hand.
Half Life 2 awards first place to the OCZ PC4000 XTC memory modules, while the Mushkin and the Corsair memories produced lower frames per second, even lower than OCZ's modules running at 400MHz. We already new that the timings are important for this test, but we expected to see similar results to the Mushkin modules. Gladly, OCZ proved us wrong.
