Suspended

Suspended is one of Infocom's more unusual adventures, placing the player in the role of a hidden computer intelligence responsible for protecting an entire colony. Released in 1983, it abandons the traditional adventurer wandering around with a sword and instead turns the player into something closer to a very stressed-out artificial intelligence. You communicate with remote robots and systems, investigate problems, and attempt to understand what is happening throughout the facility. The game is heavily dependent on information gathering and logical reasoning, making it closer to solving a complicated technical mystery than a conventional adventure. Its premise feels surprisingly modern, especially considering its age. There are no flashy graphics to distract you, just text, systems, and a growing sense that everything is going wrong at once. Suspended is cerebral, atmospheric, and occasionally intimidating, which is another way of saying it expects you to actually think.
