Christ, this looks cool!
I hope that this will make it on to Steam eventually, for workshop support and all that!
Suggestion:
Buying/selling/re-using equipment and weaponry.
Say that there is a local weapons or equipment manufactory in town, they're a tad more expensive to buy things from but if you do, the people and city hall gets happier. The other choice would be to buy equipment from China or some place, which is cheaper but will affect equipment reliability and community relations.
Additionally, if you have a surplus of old weapons that have been replaced by newer models, you can either scrap it or sell it (perhaps to the black market if you want to play a corrupt chief )
Another idea would be that you could re-use vehicles, equipment and weapons that you've seized from criminals, if you're a small department with a low budget.
Really looking forward for more updates!
