I like that idea. One thing i always though was missing was different permissions for different prisoners. Like being checked on by guards randomly as a high sec prisoner, or being able to go into more places as a sexual deviant prisoner as long as two guards are with you, like the greenhouse.
Having a max sec choice could be a fun challenging mode, where you're not allowed to buy certain items, or turning the yard into a restricted zone for you.
Talking about this also makes me really want the "Good prisoner" Route for tavi to come out. it makes me wonder if we will be tricked by the captain, or if we will eventually serve our indefinite sentence.
