I really enjoyed the campaign. I had to start chapter five a second time as my save file kept killing the game. Would be cool if they continued it to a female prison to show the heiress of the mob family locked up and running the family from behind bars. Maybe a good time to show you installing wiretaps, etc.
The campaign is really just a tutorial done in a very interesting way, which I enjoyed. Maybe teach me how to make wings of the prison different security levels? How to make my prisoners eat when there's food so they don't starve to death in the canteen? Or force them to shower so they stop getting mad about smelling bad with 4 shower times a day?
