Blade Runner is an adventure game with an emphasis on detective work rather than on puzzles. There are very few "real" puzzles in the game, and the gameplay mainly consists of questioning suspects, gathering evidence, etc. There are also some action sequences, and throughout the game the protagonist has the ability to use his gun. The player's decisions can (and will) influence the outcome of the story, bringing the game to one of the six possible endings.

I Have No Mouth, and I Must Scream is a point-and-click adventure game based upon Harlan Ellison's short story of the same title. The game's story is set in a world where an evil computer named AM has destroyed all of humanity except for five people, whom he has been keeping alive and torturing for the past 109 years. Each survivor has a fatal flaw in their character, and in an attempt to crush their spirits, AM has constructed a metaphorical adventure for each that preys upon their weaknesses. To succeed in the game, the player must make choices to prove that humans are better than machines, because they have the ability to redeem themselves. Woven into the fabric of the story are ethical dilemmas dealing with issues such as insanity, rape, paranoia and genocide.
