One way I had thought of doing this was based around a game idea I have in my head.
The idea of the game is that you are investigating some sort of supernatural occurrence in a small town with surrounding countryside area. Each game would only last around 3-4 hours, but each time you play, the town, area and thing that you are investigating are different. For example, in one playthrough you may be investigating a murder cult who operate out of a basement, and in another you might search the forests around a snowy Alaskan town for a werewolf while being hunted by the very same beast. A key feature would be that if you died in a playthrough, that would be it for that mystery; you would never solve it. Charging straight in would probably leave you dead, meaning that you would have to be intelligent in your investigation. It also adds much more horror and real fear to the game. To a lesser extent, the damage system would also be based around this; if you were hurt you couldn't just walk it off. A broken leg would pretty much be a death sentence. Another key feature would be subtlety; you probably won't get a good look at your enemy until the end of the game, if ever. You might, say if the creature is some sort of demon, only ward the creature back to its realm without ever getting to stare the monster down in battle. The only problem is the most AAA developers wouldn't want to do a game based around so much subtlety, and with the slow (though tense) pace that would be needed.
