Green Man Gaming is an online downloadable PC games retailer launched in May 2010. It allows its users to download games and then trade back their downloads when they've finished with them for credit to use against other downloadable content on the website. This works by deactivating the activation code required to play games online, which is then re-sold as 'pre-owned'.

Because the only aspect of the downloads that are classified as 'pre-owned' is the previously used activation code, it has been suggested that the website is a 'glorified rental service' and as the actual game downloaded will be new to the player, the status of pre-owned 'makes no difference to the end user'.

Green Man Gaming was launched on 10 May 2010, featuring a catalogue of 500 games from 26 publishers priced from 1p. The website was such a success that by August it had secured extra funding and was advertising additional jobs within the company.

In October 2010 Green Man Gaming announced a partnership with gaming website ComputerandVideoGames.com, and sponsored a category in the 2010 Golden Joystick awards.

A Green Man is a sculpture, drawing, or other representation of a face surrounded by or made from leaves. Branches or vines may sprout from the nose, mouth, nostrils or other parts of the face and these shoots may bear flowers or fruit. Commonly used as a decorative architectural ornament, Green Men are frequently found on carvings in churches and other buildings (both secular and ecclesiastical). "The Green Man" is also a popular name for English public houses and various interpretations of the name appear on inn signs, which sometimes show a full figure rather than just the head.

The Green Man motif has many variations. Found in many cultures around the world, the Green Man is often related to natural vegetative deities springing up in different cultures throughout the ages. Primarily it is interpreted as a symbol of rebirth, or "renaissance," representing the cycle of growth each spring. Some speculate that the mythology of the Green Man developed independently in the traditions of separate ancient cultures and evolved into the wide variety of examples found throughout history.
