''Unlimited Adventures'', sometimes called ''Forgotten Realms Unlimited Adventures'' or ''FRUA''/''UA'', is a RPG GameMaker released in 1993 by SSI Inc., which allows to create RPG games in the "GoldBox" style, much like ''Pool of Radiance'' or ''Secret of the Silver Blades''. The game's system is based on ''TabletopGame/DungeonsAndDragons'' (and is apparently a mixture of the first and the second edition). The basic world given to the player is based on the ''TabletopGame/ForgottenRealms'' role-playing game setting, but this is in no way binding.

A small but vivid community quickly was born; despite ''FRUA'''s age and the fact that SSI doesn't exist anymore, the community still exists, albeit smaller than before. Over seven hundred designs (''FRUA'' games) have been created so far, and the development of 'hacks' allowed to remove most limits and modify many things which were so far unchangeable; apart from classic fantasy designs, games have been made in Sci-Fi, oriental or even contemporary settings.

The [[http://frua.rosedragon.org Magic Mirror]] is THE repository of ''FRUA'' designs, resources and knowledge. There's also a [[http://ua.reonis.com forum]].

[[http://uaf.sourceforge.net/ Dungeon Craft]] is an attempt at a much-improved remake of ''UA'' for modern systems.

!!This game/program exemplifies the following tropes:
* ArmorAndMagicDontMix: Due to 1st-edition D&D rules.
* ArtEvolution: Comparing the oldest designs to the newest ones shows how much the community has progressed. (It also helped that computers themselves developed during all these years, allowing easier graphics editing and the like.)
* ArtificialStupidity: Computer-controlled [=NPCs=] (party members that join throughout the game).
* CharacterAlignment: Lawful, neutral, or chaotic good, neutral, or evil, as any D&D game.
* CriticalEncumbranceFailure: Averted, as movement rate decreases with increasing encumbrance.
* DivineIntervention: The "in-universe" explanation for the test mode's "instant victory" button in battles.
* ExperiencePoints: It's D&D, after all.
* FauxFirstPerson3D: In the "dungeon" levels (of course, these are used for anything from cities to forests to actual dungeons).
* FinalDeath: [[http://frua.rosedragon.org/pc/uanews/uanl34/da-gone.htm A couple of ways to do that]].
* {{Game Breaking Bug}}s: There are quite a lot, unfortunately, and part of becoming a FRUA expert is learning how to work around them.
* GameMod: Creating these is the whole point, but the hacked designs go a step further. There are even entire "worldhacks" which change the game extensively, moving it from MedievalEuropeanFantasy to a {{Wuxia}} or {{superhero}} setting.
* GameOver: "The monsters rejoice, for the party has been destroyed!" (Originally from ''VideoGame/PoolOfRadiance''.) Or, if you died outside combat, simply "The entire party has been killed!"
* LockedDoor: You can use doors locked with keys, but there are also "locked" doors (that need to be bashed or picked by means of a skill roll) or "locked wizard" ones (can only be opened with the Knock spell).
* MontyHaul: Many badly made designs shower the characters with money. One design in particular (''From Beggars to Heroes'') was content to throw thousands of money at you for the meekest reason. (For example, as poor beggars in the starting town, you can walk around and meet an unlimited number of rich people every few steps who will shower you with riches every time.) Oh, and you get experience for these, too.
* OldSaveBonus: You can import the characters from one design to another (if you know how). Designers are expected to always give the player an opportunity to save the game (and thus, the characters) just before the design ends.
* OverworldNotToScale: The "overland" levels, which are simply a big map over which you move the token that symbolizes you party.
* Plunder: One of the principal ways of getting items.
* SturgeonsLaw: Not so prevalent nowadays. Though mostly because the fanbase has shrunk to a few devoted fans who have experience with the engine.
* TheSixStats: Makes sense, as this is DungeonsAndDragons.
* UniversalPoison: Neutralize Poison and Slow Poison reverse death by poisoning, although there are subtle differences in monster immunities that can come out in monster versus monster battles.
* UnusableEnemyEquipment: {{Averted}} - you can pick up enemy equipment after every battle, unless the designer specifically turned it off for this battle. Not that it's very fun to pick up tons of useless flimsy helmets and maces off these goblins' corpses...

!!Notable games made for ''FRUA'' include:
* ''Curse of the Fire Dragon'' - An epic fantasy adventure which can readily compete with some of the finest old-school RPG's.
* ''An Oriental Alphabet Primer'' - A horror story told through word usage examples in a school textbook.
* ''Legacy of the Dragon'' - The player takes on the role of an infant red dragon.
* ''The Sect'' - You face an evil sect gradually taking over your land. Epic in scale, and contains a bit of ANaziByAnyOtherName (the bad guys say 'Heil', burn books, and exterminate people by fire) in the vaguely medieval-German setting.
