A diceless role-playing game is a role-playing game which is not based on chance: it does not use randomisers to determine the outcome of events in its role-playing game system.
 The style of game is known as "diceless" because most games use dice as their randomiser; some games such as "Castle Falkenstein" use other randomisers such as playing cards as substitutes for dice, and are not considered "diceless".

 The game was designed by Gerard Christopher Klug and published by Victory Games (a branch of Avalon Hill).

 At that time, it was the most popular espionage role-playing game.
 "James Bond 007: Role-Playing In Her Majesty's Secret Service" won an Origins Award in 1983 and a Strategists' Club Award as Outstanding Role-Playing Game in 1984.
Fudge is a generic role-playing game system for use in freeform role-playing games.

 "Fudge" has been nominated for an Origins Award for "Best Role-Playing Game System" for the "Deryni Role-Playing Game".
The Amber Diceless Roleplaying Game is a role-playing game created and written by Erick Wujcik, set in the fictional universe created by author Roger Zelazny for his "Chronicles of Amber".

This is a list of ski resorts in the German Alps.
 Because the German part of the Alps lies exclusively in Bavaria, Alpine ski resorts are only found in that state.
 The mountains in Upper Bavaria are referred to as the Bavarian Alps; whilst those in the Bavarian province of Swabia are known as the Allgäu Alps.
The alphorn or alpenhorn or alpine horn is a labrophone, consisting of a wooden natural horn of conical bore, having a wooden cup-shaped mouthpiece, used by mountain dwellers in the Swiss Alps, Austrian Alps, Bavarian Alps in Germany, French Alps, and elsewhere.
 Similar wooden horns were used for communication in most mountainous regions of Europe, from the Alps to the Carpathians.
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).
