About the base game:

Prison Architect is the world's latest Prison Management Sim. Starting with an empty plot of land you must construct a holding cell with basic water and electricity to house your first batch of prisoners, to buy you enough time to create a proper cell block. You'll need to hire some guards, get some showers built and unless the kitchen is up and running with chefs working away you're going to end up with a riot on your hands. From there you take your prison in which-ever direction you like. A monstrous super-max or comfortable centre for rehabilitation, the choice is up to you.
