I don't see much chances in this truthfully, you don't seem to get the concept very well and the way you come up with things is really slow and poorly thought of. Last time I checked, the idea of CityRPG was practically based off "realism" besides, they're nothing without realism, they need it, it's what structures them and makes them good- if done right.
Groups for cops is stupid too, everything will fall apart before you know it. I don't think you see a balance either, you should be aiming for a perfect reality for all players, good money, factories, shops, and of course- the wild things. Murder, stealing, scamming, it goes on, but from what I see you need to really get a grasp of what you're doing.
Also, yes, realism IS important in Blockland, don't deny it isn't. Because without our old pal realism, we wouldn't have some of the cool stuff on this game.
Go look at Iban's CityRPG topic for better ideas and an understanding, he had it pretty well planned out and thought of.
