Stories in media that you think deserve their own video game adaptation.

Mervyn Peake's Gormenghast books might make for a pretty awesome Ico-style puzzle game, I think; Lord knows the scenery porn alone would be worth it.

Let's be more original: a videogame adaptation of the rock opera Into the Electric Castle (by Ayreon).

Spoiler

8 persons from different time periods (an Egyptian, a Barbarian, a Roman, a Highlander, a Knight, an Indian, a Hippie and a Futureman) are transported into a different dimension by an unknown entity. To escape they have to travel together and reach the Electric Castle, while surviving the tests they find on their way.

The thing with that, and my main gripe with the album. Is that the tests are kind of vague or unspecified, and 90% of it seems more like they just get too tired to go on (and one randomly dies because the embodiment of Death shows up and picks them kind of at random). The only explicit confrontation is mainly with characters facing past guilt, which would be a very hard thing to make "gamey".

Vague or unspecified gives considerable creativity leeway on how to gamify it. It's hard only if you try to force it in an unsuitable game genre.
