Or, alternatively, alzheimers on call. One click and you can play all your favorite games. Again.
I heard that The Last Express was a game that was played in real time, and in that way you could only be in one place at one time, thus witnessing only part of the overall story. If you wanted to learn more, you had to replay the game and find a different path to go on.

From what I've heard The Last Express is one of the most misunderstood and underrated games out there.

It really does come down to whether or not you can watch a movie or read a book again. Though, like Sulibor said, Fate of Atlantis had multiple paths. You could at least play it three times and get 80% new stuff on the second and third times.

It Came From The Desert and its sequel Ant Heads did the same thing. Not exactly in real time, but with the same effect.

I've played Last Express at least half a dozen times and I can say it is right up there with Monkey Island, Indy, and Space Quest 3 in my favorite adventure games list. Every time I play I see new things. One playthrough I spent the whole time eavesdropping, deliberately losing the game, just to find out more.

Sounds nice, actually, I think I'll set this up a notch in my priority scale. The problem being, it's getting cowded up there on the scale.

I believe the ancient adventure game, Cruise for a Corpse and Maupiti Island also worked in a sort of real time.
Blade Runner, bar getting killed had 16 distinct different endings and multiple paths within that. For instance, using the CCTV camera footage, you might detect a character in the market district, but the same character is not present in another playthrough.

Also true for Lure of the Temptress.

some casual HOG already have replay value

I think of it like a movie. After a while you want to see it again, but you'll recognize big parts of it.

One game that comes to mind is the point-and-click FMV murder mystery Ripper. The clues vary between runs as does the true identity of the titular Ripper, and playing at different difficulty levels will change the solutions needed for many of the game's puzzles. I can't comment on the quality of the game itself, but the replay value is certainly there.

Thats exactly what I was hoping would happen with Heavy Rain. Lucky the game itself is so variable...
