That all sounds like a lot of technical input, and a lot of responsibility, for Roberta - who didn’t set out to pioneer a genre with Mystery House, but simply made the game she and Ken wanted to, as On-Line Systems’ debut. Earliest Magazine review- (Windows) - PC Multimedia & Entertainment (1995) Phantasmagoria is the latest offering from adventure-gaming giant Sierra On-Line. It was released for the Apple II computer - makes sense, given what hardware the pair had at home - and was the first-ever text adventure game to feature pictures of the environment or situation the player found themself in, each of them drawn by Roberta - from the outside of the building to each room and its occupants (living, or dead). The company’s first release was 1980’s Mystery House, a murder mystery set in a spooky mansion designed and written by Roberta with programming by Ken.

In 1979, Roberta and Ken founded On-Line Systems, a game development studio and publisher.
