One such title from more than a decade ago is 'RollerCoaster Tycoon 3,' third in a series of world building games from Atari, one of the world's first game manufacturers. This is the large, often undiscovered world of classic games that have been reformatted for modern hardware and it represents a treasure trove for the dedicated gamer. While it might seem like fewer games are debuting each year, the catalog of available titles is truly enormous. Like many other media forms, the library of video games continues to grow exponentially with each passing generation.
