Valve shipped Half-Life 2 with the Source physics engine, which made the world feel like a real place for the first time in an FPS — you could pick up a radiator and use it as a shield, stack crates to reach a ledge, or just throw a toilet at a soldier. The story never once stopped for a cutscene. Gordon Freeman never spoke. Every design decision was deliberate, invisible, and radical. Half-Life 2 is the game every subsequent FPS spent a decade trying to catch.
Trivia
The Source engine was entirely new — Valve rebuilt their engine secretly while fans expected a sequel
The gravity gun was added six months before ship when the team realized they needed a 'fun toy'
