I say just a developed country, a medium-large city where there is almost zero unorganised crime.
1. A medium large city has fewer large skyscrapers and
potential terrorist sites entertaining tourist attractions than a metropolis. I think that this game would benefit from having a plenitude of interesting locations.
2. With no unorganized crime, the police will swoop in and arrest most of us for carrying illegal weapons. So far, what basically everyone else has agreed on is that having the police show up when all you have is a combat knife and a revolver is not going to make the game entertaining or worthwhile.
We need a place where we can slip under the radar until we can actually deal with law enforcement. At that point, we need them to actually pose a threat. In other words, we need a city with a large police force that's currently busy handling the populace. Setting the game in a metropolis would provide a population large enough to occupy the police, many interesting locations, an increased likelihood of locating illegal firearms, and enough space that the squads could all do their own thing without accidentally stepping on each other's toes.
What about a well-developed city with low-level organizied crime. Just a couple gang.
That's probably a good idea too, if they were very small street gangs. I agree with Archangel, too. I'm not sure what constitutes mid level unorganized crime, but it sounds unorganized.
Or we could set it in a massive city riddled with relatively unorganized crime. That way, the cops will be too busy tracking down pedophiles and miscellaneous psychopaths to worry about us until we start buzzing residential areas in a helicopter, dropping bombs and spraying houses with minigun fire while Dies Irae from Mozart's Requiem Mass in D minor blares loudly out of our helicopter-mounted speakers at 194 decibels.
And by then it'll be too late.
YES.
I'm glad you share my enthusiasm.
