Every time I start messing with dcity, I find I spend waaaay too much - except this time.
I took your advice and sold most of my workers for basic homes and luxury homes. I also took my criminals off the market and spent experimented on them: gained a bunch of sick citizens, but also won a super criminal and super cop! Bought some clowns and burned some communal housing.
Just another day in dCity.
I have something for the sick citizens coming out soon! Will keep you updated :)
