A rules-light 2-page TV series simulator, Police Cops works best with 4-5 players, and one Commissioner. The Commish is the GM. The game is designed to play like a cop show, each session or two being an Episode with its own enclosed story, but still part of broader series.
Before you begin playing, there's a few conversations you need to have around the table. Firstly, this is Police Cops; you need to have a premise for the game. The more hackneyed and ridiculous the better. TV is rife with examples, just waiting to be plagiarised. Maybe you work on cold-cases, by investigating crime scenes, for a special victims unit brought in by the NCIS to look at bones. Choosing a theme song helps with this step. Maybe something by The Who?
