Fudge (role-playing game system): Fudge is a generic role-playing game system for use in freeform role-playing games.  The name ""FUDGE"" was once an acronym for "Freeform Universal Donated" (later, "Do-it-yourself") "Gaming Engine" and, though the acronym has since been dropped, that phrase remains a good summation of the game's design goals.  "Fudge" has been nominated for an Origins Award for "Best Role-Playing Game System" for the "Deryni Role-Playing Game".

Forgotten Realms: Forgotten Realms is a campaign setting for the "Dungeons & Dragons" ("D&D") fantasy role-playing game.  Commonly referred to by players and game designers alike as "The Realms", it was created by game designer Ed Greenwood around 1967 as a setting for his childhood stories.  Several years later, Greenwood brought the setting to the "D&D" game as a series of magazine articles, and the first Realms game products were released in 1987.  Role-playing game products have been produced for the setting ever since, as have various licensed products including sword and sorcery novels, role-playing video game adaptations (including the first massively multiplayer online role-playing game to use graphics), and comic books.  The Forgotten Realms is one of the most popular "D&D" settings, largely due to the success of novels by authors such as R. A. Salvatore and numerous role-playing video games, including "Pool of Radiance" (1988), "Eye of the Beholder" (1991), "Baldur's Gate" (1998), "Icewind Dale" (2000) and "Neverwinter Nights" (2002).

OSv: OSv (stylized OS) is a cloud computing focused computer operating system released on September 16, 2013.  It is a special-purpose operating system built to run as a guest on top of a virtual machine, thus it does not include drivers for bare-metal hardware.  It is a unikernel, designed to run a single Linux executable or an application written in one of the supported runtime environments (such as Java).  For this reason, it does not support a notion of users (it's not a multiuser system) or processes - everything runs in the kernel address space.  Using a single address space removes some of the time-consuming operations associated with context switching.  It uses large amounts of code from the FreeBSD operating system, in particular the network stack and the ZFS file system.  OSv can be managed using a REST Management API and an optional command line interface written in Lua.

Living Steel: Living Steel was a high-tech role-playing game published by Leading Edge Games and based on their Phoenix Command game system.
