PC games are not known for their collectibility, especially when compared to rare games for popular video game console systems like the Nintendo Entertainment System. PC games do not hold their value very well and the platform simply does not have many of those hard to find and highly sought after titles. This is largely because PC games are one of the most readily available types of video games that can be obtained, whether it be through legal or illegal means. Legal digital distribution of PC games through download services and distribution platforms like Steam has changed the landscape of PC gaming. PC game piracy and older games being abandoned or released as freeware have also had an impact on PC game distribution. The combination of these has reduced the need or desire for PC gamers to own a physical copy of a game.

Despite the limited value and collectibility of PC games, there are some highly sought after titles that can fetch a decent price on secondary markets like eBay. The list that follows contains some of the most valuable PC games and includes both older titles as well as limited collector's editions of newer releases. The criteria used for the most valuable PC games list was PC games sold on eBay in the past 90 days starting from July 2015 and primarily includes auction listings but also includes a few buy-it-now listings.
