Shadowgate

Shadowgate is a 1987 point-and-click adventure game originally released for the Apple Macintosh by ICOM Simulations, and is part of the MacVenture series. It has since been ported to a variety of platforms. Originally in black and white due to the lack of color on the first Macs, a color version of the game was released the same year for the Amiga and Atari ST, and in 1989 for the NES.

The game is named for its setting, Castle Shadowgate, residence of the evil Warlock Lord. The player, as the "last of a great line of hero-kings" is charged with the task of saving the world by defeating the Warlock Lord, who is attempting to summon up the demon Behemoth out of Hell. The player takes control of a relatively faceless character who must traverse through the castle avoiding many obstacles and choosing the right course of action to proceed.

The player must solve a series of puzzles throughout the castle to proceed to the Warlock Lord's chamber. Due to the castle's perilous nature, at least one lit torch must be in the player's possession at all times. If the torch is extinguished, the player soon stumbles, breaking his neck, and must then continue from a saved game (or the area in which they died, in game console versions). Only a finite number of torches are to be found throughout the game, which effectively acts as a time limit to proceedings. Various items that can be acquired include a sword, a sling and other ancient weapons; though these weapons can not actually be used as striking weapons, they can be clicked on at the appropriate time to deliver a fatal blow to specific enemies.

The game is notorious for its many opportunities for death, including being burned by a dragon's breath, attacked by a cyclops, sucked into outer space through a broken mirror, dissolved by acidic slime, mauled by a wolf-woman, eaten by sharks, and suicide. Virtually any action taken by the player which is not the correct solution to a puzzle will result in a fatality. These deaths were often graphically described in the game's text (along with often sardonic and humorous comments), even in the NES version (in spite of Nintendo's policy of censorship at the time).

Many of the game's puzzles rely on a system of trial and error, the problem of which is overcome by the ability to save the game state (as in most adventure games). Subtle hints can be found in books and the descriptive game texts. In the NES version, these are replaced by an outright hint feature which gives vague clues about what is noteworthy in any given room in the castle. The further the player progresses, however, the more useless this feature becomes, deteriorating into nothing but encouraging messages by the game's end.

Story
From the game's introduction:

"The last thing that you remember is standing before the wizard Lakmir as he gestured wildly and chanted in an archaic tongue. Now you find yourself staring at an entryway which lies at the edge of a forest. The Druid's words still ring in your ears: “Within the walls of the Castle Shadowgate lies your quest. If the prophecies hold true, the dreaded Warlock Lord will use his dark magic to raise the Behemoth, the deadliest of the Titans, from the depths of the earth. You are the seed of prophecy, the last of the line of kings, and only you can stop the Warlock Lord from darkening our world FOREVER. Fare thee well."
