1984 - BBC Micro\Acorn Electron - Classic Adventure

Classic Adventure was the first major computer game and now it's become a classsic in its own time. This exciting new release of Classic Adventure for the Electron will enable you to slay dragons, find hidden treasures and bribe trolls: and as your skill increases through more and more victories and discoveries, you too can become a master adventurer.
Before Crowther and Woods wrote ADVENTURE in 1978, games all had something more or less in common. The player knew the rules, and had to try to use them to get the best possible score. In an Adventure, the aim of the game if to discover the rules!
To do this, the computer acts as your eyes and hands. It will tell you where you are and what you can see. You can tell the computer what you would like to do by giving it simple one or two word commands like "THROW AXE", "CLIMB" or "DRINK WATER".
The aim of the game is to find the many fabulous treasures hidden, and often guarded, in the Colossal Caves, and get them back to the building. But take care! Magic is said to work in the caves, and things are not always what they seem! Many things you pick up have strange side-effects and there are shady and often unfriendly characters lurking in the dark.
Typing "INFO" will get you some general information about playing Classic Adventure. To see how well you are doing, type "SCORE". "HELP" may be helpful at times. "INVENT" gives you an inventory of what you are carrying. "QUIT" allows you to finish the game.
Don't forget the caves have very twisty tunnel so if you go "NORTH", going "SOUTH" doesn't always get you back where you were!
Hints
The computer only uses the first four letters of the words you enter so you can save time by typing "TAKE SILV" rather than "TAKE SILVER". The direction commands can be abbreviated to a single letter. If you have tried several different ways to do something without success, it probably can't be done. Try dropping something, or move on to comething else - there's plenty to see in the Colossal Caves. Experienced adventurers generally make maps as they explore, and although mazes are difficult to chart, it can be done! If you get really stuck, go adventuring with a friend - they may think of something you haven't.
And remember the etiquette of adventuring - revealing the tricks is like announcing the end of a whodunnit - the act of a cad!
