Half-Life 2 hailed a new era of the role physics engines play in video games. One of the first games to showcase the Havok engine, Half-Life 2's success spark the creation of 3rd party physics engines. This now allows developers to focus on design, so rather than having to program a complex physics engine from the ground up, developers can now pay a fee to utilize a pre-existing one.
