Wealthy Derrick Reardon is murdered in his Long Island mansion. There are few suspects on the estate and you, as Detective Stew Cavanaugh, will have to find the killer through the dialogues and observation of them all.
In 1980s full motion video games (FMV) looked like a perfect way of mixing video games (that struggled with graphical presentation of the gameplay) and movies - real actors were playing scenes that were later compiled so the story could take different routes depending on decisions of the player. In practice it rarely actually worked - the decisions usually had marginal influence on the story itself, however, there were exceptions. Like MysteryDisc: Murder, Anyone?, where 16 different endings were implemented in the game, which at least gave the game above average replayability.
Of course they were still pre-made storylines, so it was not in any way open ending game, but at least the creators made some effort.
Can you solve a case like this?
