IGN - Coming up with top 25 games lists is never an easy task. There are so many incredible products out there built by such talented people that deciding which make the list and which just miss it can be a painful process. The reality is there's only so much room, so invariably amazing titles have to be left off. As you may have inferred from the title of this article, this is not a list that spans the entirety of PC gaming's existence. In an effort to make the list more current, we've limited it to the modern era of PC gaming – from the year 2000 to today.
