Does anybody have anything specific that they would like to see in this mod?
Yes.
Crime and Judicidal systems.
If you played Phoenix Wright or any similiar games, you will know where i'm going.
Basically, if the crime is comitted, there will always be some kind of evidence: gun powder, burnt clothing, stabbing wound, broken vase, gunshot in the chest, fingerprints, etc.
Players can find that stuff as an evidence upon close examination of objects. Examining dead body of the player (Let bodies stay after death), they can find evidence that can be seen by a normal eye, like wounds and burnt clothing, but sometimes, the criminal can tamper with evidence: Clean blood or fingerprints off, purposefully put victim's fingerprints on the knife to make it seem like Self Delete and all that.
That's when special detective shizz come in. Where there was blood, even after cleaning it off, there still is blood marks invisible to human eye.
Glove marks also should exist, so you can detect that someone indeed tampered with the evidence.
All of this results in a very intriguing crime scene. What has been "OMG RDM!!1!!" previously now has a deep insight on what happened. Since there will be no killfeed, players will have to discover the killer with their inner detective. I find that concept very loving fun so I really hope you do it right in City cubed :D
And about judicidal system, I suggest playing Phoenix Wright: Ace Attorney on Nintendo DS to get some ideas. It will take a long time to explain how it should work, so I guess I leave that one to you.
