Procrastination stroke

How would an atmospheric adventure game work? I've been working on a cyberpunk plot, and I keep reverting to cinematic techniques to make the whole idea work out. But a game desires of gameplay. I've probably caught myself watching too many movies lately, but that has worked as an inspiration. Yet, the gameplay element eludes me.

I'm leaning towards playable memories, as it fits the setting a lot, but, how do you have playable memories?
Yume Nikki, what have you done to me?!
