Let them meet their people:
- General visitors: Build non-contact visiting rooms (those glass windows with phones)
- Family: Build visiting areas (simple playground with benches and heavy visitor and prisoner checks. This will introduce contraband!)
- Partners: Build, ahem, trailers. This will cost the prisoners money for "rent" and you will earn back those dollars fast
EDIT: Additionally to the rent, you can also sell the couples heavily overpriced red wine, peanuts, crisps etc.
Just got the Alpha a few days ago, really exited for what things are comming next. I loved all the bullfrog games, so I was striving for something like this xD
