Not sure I'm fully aware of which things you're referring to, but it sounds awesome. Blackgate is the visual novel, right?

Blackgate is/was the prison in the DC universe when arkham isn't an option because they are just evil, not insane.

Oz was a tv series on HBO from 97 to 03 and really 'harsh' look at the prison system.
