Half-Life 2
Half-Life 2 is just one of the multiple classics that Valve corporation has created during the beginning of their existence when they were purely game designers. Now that Valve owns Steam (the largest video game marketplace in the world by an 80% margin), most of their focus and tools have gone to maintaining the most profitable business in the entire gaming industry. That being said, the Half-Life series cemented Valve as a serious studio, and without this groundbreaking game, there would be no Steam.
