I was listening to the Heavy Rain soundtrack when I got this idea.
Now, I know a shit load of people CONSTANTLY say, Oh, what if you take X game/genre and make it huge like GTA!! But what about if you have a detective game in a GTA shell? I'm not talking just that you're playing a cop in GTA. There's a difference between just being directed to your objectives, and having to find out yourself.
So what I'm saying is that let's say you find a origami in a crime scene. Instead of like in GTA, where you're told: Go to the Origami shop (minimap expands and shows origami symbol), you have to be smart and figure it out yourself.
So the gameplay consists of this:
1) Evidence gathering gameplay like in Heavy Rain, except without the glasses.
2) Evidence finding gameplay like in Heavy Rain, except less limited and guiding. For instance, to find the origami shop, you'll have to google or yellow page up the shop. Rather than the character just automatically pulling up the map, and finding it.
3) Action/chase scenes/Suspense momments/etc. This is where the GTA gameplay is.
You can have lots of side missions, like GTA, by going to mission (crime scene) and solving it. I'm thinking that you can mandate completetion of these side missions, by having supplmentary clues pop up with them.
