Based on the anime death note.

Quote: A Death Note is a book held by a Shinigami which has the power to kill people if certain conditions are met. All Death Notes follow a long set of specific rules, and the writer revealed a few of these rules with each volume of the manga in Japan. [edit] Rules of the Death Note Main article: Rules of the Death Note [edit] Written rules * The human whose name is written in this note shall die. * This note will not take effect unless the writer has the subject's face in their mind when writing his/her name. Therefore, people sharing the same name will not be affected. * If the cause of death is written within 40 seconds of writing the subject's name, it will happen. * If the cause of death is not specified, the subject will simply die of a heart attack. * After writing the cause of death, the details of the death should be written in the next 6 minutes and 40 seconds.

http://en.wikipedia.org/wiki/Death_Note ->3rd person camera ->Multiplayer game ->Takes place in a similar environment to the recent Spiderman, Superman, Hulk type games. By that I mean a large city, civilians running around, random robberies/attacks. ->Requires a conversation system, for the kira to acquire the name of the person The game takes place in rounds. At the first round, a random player is given the death note, and becomes the kira, the other players are police officers. The polices objective is catch the kira. The kiras objective is to kill as many evil doers as possible. ->Some kind of a scoring system, 1 point for regular civilans, two for criminals. ->There are teleprompters around the city, that display the news telling of criminal names. ->As the kira kills more people the world becomes brighter As the kira: In order to kill a person you must be thinking of them, and write the name in the death note. Implementation idea: Have a list of faces, and another list of names, they should be come jumbled up as more names are added to your list. You have to match the face and name to kill the person. When you kill a person you have to draw out your notebook. "Death gods only eat apples" The world/city should be filled with apple vendors. Ryuk, a death god, will have an apple timer, when the timer reaches zero he will 'have' to eat an apple. Ryuk can only be seen by people who touch the notebook, so as the apple is being eaten it will be floating in the air. ->The kira have a time limit to how long they live ->The kira is also given the option of obtaining demon eyes, which allow him to see true name of the person. He loses half the time he has remaining. ->Officers revive if killed, after a penalty timer at random police station The player who catches the kira, becomes the kira the next round. There is alot of things missing, such as a penalty for arresting the wrong person, etc.. but it was just a quick idea.

This forum is for stories and also does not allow fanfiction, sorry. Try the game design forum if you're serious about producing a fan game though.
