I nearly forgot.... Blade Runner!
I believe it's one of the best adventure game ever made (c)
Not only it didn't rely on the story of the movie but it really gave the players choices at different scenes of the game. If I remember well.. there were 16 endings! Ok, they were in fact 4 main endings with variants depending on the characters of the game.
It's strange that I never read anything comparing this game to Fahrenheit but BR felt more like an interctive drama for me
