... People should really not let me peruse the interest checks anymore. Really. I have a problem. 

In other words, I'm in freaking LOVE with this idea. Reminds me of long-running crime series like Criminal Minds, which I would assume is your intention. 

As well you seem like a good writer and I'd love to help you brainstorm this, if you'd have me. World building and plotting are like, my pastimes. If anything I can just spitball some ideas around. 

Right off the bat my first suggestion would be to have a definite player cap, say, 5 characters or less at any given time. I also like the idea that players couldn't pull clues out of thin air to magically solve the case. This means that you'll not only need good writers but the characters would also be more realistic, as they'd need to be written to the writer's strengths. For example, it would be very hard to write the team genius if the writer is less of a problem-solver, know what I mean? 

In a perfect world, something like this would run and stay running for a long time. That means that this is actually a pretty good venue for a turnover of players. If someone has to leave the RP for reasons it's easy to write them out as a plot point (they get shot, transferred to another district, etc.) I'm sure you've thought of this already but hey, I just love the sound of this. 

I'm probably way ahead of myself here but I hope I said something coherent. It's late, h e h.
